Using the same logic you could argue you can’t walk into the room with any clothes on.
It doesn’t say you can’t throw them into a massive container lined with repelling magnets that’s located out the door - so you aren’t technically “putting them down”.
The rules are quite sloppy. It doesn’t really matter whether or not you can pick them up and set them down, given that once you leave the room you’re done. Like, what does that even add to the challenge?
If we take it quite literally, does that extra rule mean you now can never pick up ANY coin you’ve ever picked up previously in your life ? Wouldn’t that be weird trying to collect change from a cashier and like a quarter immediately disassociates from your hand and you can’t grab it because you handled it once back in 2003?
But sure just make a deal with your friend to bank the coins for you and take a 10% cut or whatever. You don’t personally have to handle them.
Pick up as many as you can fit in two hands and walk out. $20-$30 billion is plenty. In fact it’s perfect because you’re not richest guy in the world famous but have eternal fu money for you and even your extended family.
Maybe that’s the “trick” of this supposed question. The answer is a handful enough because they are $1 billion coins. However to me, the proper way to read this is that each coin is worth $1 billion. Otherwise it should say 1 billion $1 dollar coins.
For example switch the word coin with bills. If you said “imagine you’re in a room with 1 billion dollar bills laying on the floor”. Would you assume they were $1 bills or $1 billion dollar bills?
I used to work at a bank that had a coin counting machine, and we'd get these coin collectors that would come in every month to buy an entire box of quarters or dollar coins, go through them, and then later bring in a bucket of the loose coin that they didn't keep. Those buckets were heavy. And then the machine would sort the coins into bags, and when the bag filled up, we'd have to seal up the bag and put a new one on. Those were heavy too. The Brinks guy would bring a cart to take them away.
True... Where to spend them.. maybe put them back in this room and then have even more challenging wording and instructions on how to about this experience 😁
According to a previous post (on mobile so sorry if that formats wrong) a dollar coin has a volume of .0675 cubic inches.
Multiply that by a billion and you get 1,106 cubic meters (according to wolfram alpha). Stacking won't be perfect, so the actual volume would be more than that. You're looking at about half(ish) the volume of an Olympic swimming pool. You would need to look at how efficient randomly dropped coins pack (or the efficiency of whatever the packing system is) to come up with a more exact sense, but that gives a good sense of scale. It'd be crazy heavy, btw - about 8,000 metric tons.
EDIT: here is a post about coin packing efficiency. Pennies aren't dollar coins, but this means that our volume estimate is closer to about 80 percent of an Olympic swimming pool, with much of the volume just being air. I imagine someone has done engineering research into random coin stacking problems for e.g. vending machines and parking meters, so we could probably find a better number somewhere.
There is a 10 dollar coin thats much smaller than a dollar coin. It is made of gold, so its much denser than if it were copper or zinc. But, if the floor were covered in those, I'd be fine with just filling my pockets as much as I could hold. probably swallowing a few for good measure too. And anywhere else they would fit.
a $10 gold coins worth about $2500 give or take , just under 17 grams of gold , personally im not greedy id be happy with just a pocket full never mind a rooms worth
I thought the same thing as u/Astrochops ("A scheme to collect as many as possible! Why bother, when I'm not going to notice much difference between 1 coin and 100 coins.").
I feel like they should've used a hyphen (1 billion dollar-coins), or phrased it less ambiguously (1 billion dollars worth of coins).
That is pretty ambiguous and and can be reasonably interpreted as “1 billion coins worth a dollar” or “coins worth 1 billion dollars”. TBH, wouldn’t be surprised if it wasn’t phrased that way to create engagement.
Because the premise is actually kinda lame. If it’s $1-billion coins pick one up and neither you nor your family will need to work again. If it’s $1 coins you’re not going to pick up a life changing amount.
Excluding stacking issues, how would you calculate the least negative space needed between the coins for them to fit best together and figure that into the calculation?
Vertical you can do perfectly. That's not an issue. The circular element is the problem, and you can get that to just under 91% efficient. So, you'd wind up with about 1,200 cubic meters.
That’s closest packing of circles, in a 2d plane. What about cylinders? I’m guessing it’s basically the same, just adding a stacking height limit, but you never know. There’s some weird closest stacking scenarios out there.
All the gold ever mined in humanity fits in like 3 to 4 Olympic swimming pools. All the wars, all the millions of gold miners, the millions sacrificed to the dark gods, etc. And yet we could fit it all inside a single warehouse.
Right? You only need to carry them out the door. Fill the bags next to the door then find the 10 seconds of strength to lift with everything you can for 2-3 steps.
Sais i can't put them down and pick them up later.
DOESN'T say i can't just toss them out the door directly into a waiting tip truck. Fill it to the brim. And drive it to the nearest bank.
Technically "I" will never pick them up again and the truck qualifies because it doesn't enter the room with me. And isn't a tool. Just my mode of transport too and from. 🤷♀️
This is the right idea, but we need to think bigger. We need to hire a team of 18-wheel tractor trailers and fill them all up. Bring a 10cm container of water and work until you are completely dehydrated/starving.
it also says once your hands leave the room youre done but nothing about the rest of you, so you could easily just kick them through the threshhold to avoid any accidental "leaving" via hands crossing the line during a throw
This question is likely to be engagement bait based on the poor wording.
If the floor has scattered upon it many coins each individually having face value USD 1,000,000,000, depending on what the state of the economy is outside, a pocketful might suffice.
If the floor has coins of face value USD 1.00, whose total quantity is 1 billion, I'd ask Reddit for someone to do the thinking for me.
Also it doesn’t make sense to have over a million dollar coins because that is more than anyone on earth can lift at 8,100kg.
As for the question I would cheat at throw them out the dollar as it says I can keep any that I lift until I leave the room, by throwing them out I don’t have to worry about mixing them up. I would like some gloves and or a scoop of shovel or something.
10cm bag that collapses to a compliant size but has a maximum capacity much larger. This is assuming the bag counts as "holding" it, since a tool like a trowel is technically not holding with your hands.
I'd take a 10 CM roll of fairly thick fabric, like denim, and set it up as kind of a slide out of the room. Then just pour coins in the top and let them slid out the door.
This is the way. Bring a folded up tarp, fill with coins and drag it out. This is a great way to move dirt when somewhere a wheelbarrow won’t work, just pull dirt onto the tarp and drag.
Most people don’t understand how much a billion dollars is. One fucking coin. I not taking any more, what’s the point. I’ve won the game I’m fucking out. Generational wealth and never worrying about the lights or water turned off. Yeah just one, that all I need.
Easy, cut one hand off and leave it in the room. Go outside rent a bulldozer and open a hole on the ground. Get back to the room and break the walls, fill that front bucket with coins then dump them at the hole. Repeat for a couple hours then go to the surgeon get your hand stitched back.
A full bucket shoud have ~10 million coins times 1 billion = 10 quitillion dollars. Depending on how any trips you can make multiply that number... or maybe just let the hand rot?
If you use 100 billion pennies, it would occupy about 2,000,000 cubic feet if optimally positioned. If you use $1 coins, it would occupy about 50,000 cubic feet if optimally positioned.
Diameter of a penny (dollar coin): 0.75 in (1.043 in)
Depth of a penny (dollar coin): 0.06 in (0.079 in)
Not quite optimal - you can actually pack coins tighter than you could boxes that bound them. Take a coin and surround it with six more coins in a hexagon. If you were to draw squares around each coin, the corners of those squares would overlap.
A 10cm folded bag/tarp can be very big once unfolded. You can spend all the time you want in there, so you don't need gizmos to pick them fast, you just need storage.
I'll get one of those 1m³ canvas bags that builders use for sand etc. and turn it in to a very chic hat! Once inside the room I'll simply remove the hat and take a 1m³ pile of coins with me.
I had considered a pair of pallet truck roller stakes as well as an alternative.
If it’s (coin worth $1B each), and they are a common size for coins, just grab enough to satisfy your stretch goals.
If it’s 1 Billion coins that are one dollar each, then things get harder.
If they are the modern gold color ones that would weigh 8.1 million kilograms. 182 kilograms (400lb)worth $22,446 would fit in a 36 liter medium sized backpack. An ultra light day pack should compress into the tool size required.
If you’re using “1$” Silver coins, the same weight and setup would get you $5,845 face value and trade for ~$146,140 and reasonably up to three times that.
My tool would be a parachute canopy folded to the size limit. Unfurl that fucker and start dragging coins into the chute until you can't lift it anymore.
I read this as each coin has a value of a billion dollars. I probably wouldn't even over think it. Pick is many as I can up. Probably 100 or so, and just leave with 100 billion. That's plenty of money.
But if it's normal coins like quarters and shit... There is no way you are going to be able to get anywhere near the whole billion even if you were allowed to use a wheelbarrow.
I think Most people missed the “1 billion dollar coins” part. I’ll take one for myself and a few more to donate to Wikipedia, Mozilla, United Way, and what ever other charities I can hold coins for.
Given a dollar coin weighs about 8.1g and an average person can lift about 60kg (let's go with 81kg just for the sake of it), you could carry about 10k dollars with optimal stacking/packaging.
maybe if you could get a very sturdy but light fabric (parachute maybe). So the fact that there are 1 billion coins doesn't really matter, as you couldn't even get anywhere neary 1million or even 100k. not even the strongest person alive could do that.
The room contains "billion dollar coins?" if the coins are worth a billion dollars then I only need one. I'm good with that. (I know you just worded this wrong lol)
Seems pretty self evident that you just cheat and toss the coins out the door until they are all out the door. You can even push them with your feet if you like apparently. Your hands are the only thing that cannot leave the room. So just keep tossing or shoving them out whatever constitutes the way out until you have your billion or whatever and then leave.
Pick up 3-4 come out and give away all but one to charity, living happily ever after on the interest from one billion and then give that money away on my deathbed.
Very open to interpretation. You could be in a very small room that is unbelievably deep. In this case the size of the room is equal to the volume of a billion coins of whatever currency you pick (doesn’t specify USD, CAD, AUD, etc. lots of countries use the term dollar for their currency)
Or we could assume it’s a massive warehouse with only 1 layer of coins in which case you could roughly estimate by surface area. But the rules don’t specify how spaced out the coins are just that they are scattered on floor.
Again it depends since the wording isn’t great. They simply asked what volume of space would it occupy. They didn’t specify if they are talking about the coins or the room. Poorly worded question as are most on this sub.
Don’t know why people struggle to read this problem so much.
One billion objects. The objects are dollar coins.
A dollar coin is about 1.09 cubic centimeters. If you could stack them perfectly, about 1.09 billion cubic centimeters total. (About 1090 cubic meters, roughly 40% of an Olympic swimming pool)
But “scattered on the floor” suggests inefficiencies in the volume arrangement. If it’s tightly packed perfectly in a flat layer, you’d add about 10% for gaps between coins. (Perfect circle packing covers about 90.7% of a flat area).
Allowing for some overlapping coins in multiple layers, and irregular packing from “scattering “ I’d probably use more like a 33% loss of volume covered. This is purely assumption trying to guess just how disordered “scattering on the floor” looks. At this estimate, you’d fill about 50% more volume than a clean stack, yielding about 1500 cubic meters, or about 60% of an Olympic swimming pool.
So each coin is worth 1 billion dollars or there 1 billion dollars worth of 1 dollar coins scattered on the floor? 10cm tool in total size, or squared/cubed? Could I use a u-channel of any length as long as it’s 10cm in height and width and just roll coins out of the door as I’m technically not putting them down? The situation ends when just my hands leave the room? It’s all very vague! I’m not going to do the maths. Ok I’m going with the coins are worth I billion each. Fuck the 10cm tool. I’m wearing an enormously oversized and zip up boiler-suit, I’m pushing as many of the coins over to the door way as I can, I’m laying down on the floor and filling my boiler-suit up with the coins and creating a nice stable base to then place more coins on top, then when I’m ready I’ll put my hands through the doorway. After that I’m going to give all but one coin away trying to solve the world’s problems. With my remaining coin I’ll see all of my family and friends are taken care of and live on some out of the way land with hundreds of dogs.
Wait - you could read that as each coin is worth one billion. Just pick up five or ten and leave. If the coins are only 1 dollar (there’s just a billion of them), nothing you could do within the rules makes the exercise worth it.
I would bring my cell phone into the room. I would call my family and ask them to rent a dump truck and buy several gallon buckets. I would push coins to the edge of the door and they would fill the buckets with coins and then put the coins into the dump truck. Once the dump truck is full they would bring the coins to my family’s farm, dump them, then return for another load until all the coins are removed. I would split the money evenly with them. This would likely take several days but I’m too lazy to do the math on how long it would take
A bucket measuring 10cm on all sides.. fill it up and fling the coins captured in the bucket outside the room... Keep doing this til your done. Then walk out the room.
(to fit the dimensions of the prompt, they didn't say how this 10cm was measured. I'm thinking here like some kind of airline baggage check thing for entry to the room or what, so for fun I'm assuming it's a "must fit in this box" check at the door)
The wadded up Basic D&D (circa 1980s rules) version of the bag of holding. (of which OSE is a direct retro-clone of).
Bag of Holding
A normal-looking, small sack that can magically contain large objects and weights.
Size: Objects of up to 10’×5’×3’ can fit inside the bag.
Weight: Up to 10,000 coins of weight can be placed in the bag.
When full: The bag weighs 600 coins.
Now to translate that, in Basic D&D a "coin" of weight is 1/10 of a normal (avoirdupois) pound.
In later AD&D this was reduced to 1/20 of a pound. The actual weight of real world large gold coins, depending on the size, is somewhat in-between those numbers.
Sticking with the Basic D&D source material let us directly translate this coin weight into real world weight. that is 1000 customary US pounds and note that the linear dimensions ONLY refer to the size of any one object here, not the entire magical space of volume (unlike in later AD&D or later D&D). So ignore volume, only weight matters. As a side note a full Basic D&D Bag of Holding does weigh considerably more than most versions that came later, 60lbs vs 5lbs, but the brokenness of the limitless volume is great.
So, using the objectively broken version of the Bag of Holding every officially published, you can store a 1000lbs worth of real world dollar coins.
According to the Googles, the modern US Dollar coin weight only 8.1 grams exactly.
One pound = 453.592 grams
1000 pounds = 453592 grams
55999.012345679 US Dollar coins, so actually 55999 coins with the last one over just being spat out due to magic shenanigans.
So $55,999 dollars worth of modern US coins as legal tender.
Now of course if the "dollar coins" in the prompt are some kind of actual historical gold dollar coins this throws the numbers way higher, if assuming intrinsic or numismatic value.
I'm not a mather but I do have a solution to this very odd query - I'm bringing a keymaking/lockpicking tool known as a Lishi. One of it's functions is to allow you to decode the tumblers in the lock so you can copy the pattern onto a new key. Bam. Whole room is mine now! I can come and go as I please lmao
(And before anyone asks, of course I always keep a set of files and a blank key on my person... There is absolutely zero way the proprietor of this odd money room can tell me I don't and therefore, they are not additional tools 🤣)
The issue is more weight than volume or speed of picking them up. I know I can carry about 40 kg in a backpack for considerable distances, but my limit is somewhere around my own weight of 70 kg. That's $8642 dollar coins, each 8.1 g. That's just 4.6 L in volume.
I'm sure there are powerlifters that could easily handle twice that, but its a less generous giveaway than one might imagine.
Now, if the room was filled with $50 face value 1 oz gold content American Gold Eagles, the same 70 kg would permit collecting 2063 coins, with a spot value of $8,866,774, and volume of 1.94 L.
At my physical peak, I carried just over 300lbs about 50 feet (25 years ago). Currently, I know that even that amount of coins wouldn’t cover my (USA) copays for the eventual hospital ER visit for trying. So, I’m grabbing about $3000 and calling it good. 😁
Easy, the tool I'll use is a cell phone to call someone to come get the coins for me. There's also no rule about just throwing the coins out of the room and leaving afterwards.
I’d bring a 10cm cubic box. I’d also dress in layers.
Fill the box with coins. Then take off as much clothing as I’m comfortable taking off (my comfort level will increase as I get more money I’m sure), tie the clothing articles as needed and fill those.
In Canada, the largest face value coin is the Big Maple Leaf marked at $1M CAD and weighed 100KG. Its volume is about 5L. So 1000 of those coins so 5000L or about 5 cubic meters. Not that bad.
Contractor bag with the highest mil rating you could find. I'm pretty sure it could fit in a space less than 10 cm. Since there would be a barrier, you'd be able to at least walk out with 100 lbs worth. At 8 grams a coin, you're basically walking out with 5700$. If they're silver dollar coins, that's 1750$ face value and 1458 troy ounces. That's about 88,000$ worth of silver at today's prices.
I guess duct tape, as much as possible in a roll, no hollow center.
I start making stacks and covering them around with 1.5 rounds of duct tape and then the next row of coins and so on.
Eventually you end up with a giant coinc sushi made of many mini Coin sushi.
It's the only way I can think of how to be able to take out as many coins as possible in 1 go.
Eventually, I need to find a way to make a ramp out of the other coins to roll the coin sushi out of the room because there is no possible way you can lift that monster roll without any tools.
Now the question that remains is, what if I roll the whole thing out of the room but I don't leave the room? Will those coins count to my advantage and I keep making giant rolls?
Assuming the tool specs would allow, get a 10cm wide roll of duct tape, laying them out side to side you’d get 5,440 assuming the coins are the size of an American quarter and the industry standard length of the duct tape, which would be 100mm wide and 33 metres long, the most common result using Google. After that tie off your trouser legs and fill those puppies up. Volume obviously dependent on whether you prefer skinny jeans or parachute pants so your mileage may vary. Either way you’re leaving 99% of those coins in the room.
The rules don’t say you can’t hire outside help though, you could throw them one at a time over the threshold so your hands aren’t leaving the room and you’re not picking them back up again. Might take you a while but you could get every one of them out of there.
He said once your hands leave the room. I’m taking a 10cm2 sheet of plastic and scraping the cone out of the room, being careful to never let my hands leave the room while doing so.
Amazing how many comments are litigiously dissecting the hypo w/o even playing along...I say this is a stacking game...how many stacks of coins, however denominated, can i balance long enough to get over the doorway? my 10 cm tool would be a tube of qiuck-dry water soluble glue.
Per the title. Each coin is 1 billion dollars. They mention “coins” as plural. So there can be 2 or more coins on the ground. Since they did not mention how many coins are on the ground, the default is 2. Therefore, hardly any space at all.
Assuming USD “gold dollars” currently in circulation, then each coin has a thickness of 2mm and a diameter of 26.5 mm.
If made into a tower, 1 billion coins would be 2,000 kilometers tall, with a volume of 1,103 m3. To fit all that into a room you’d need a space that’s 20m on each side and 3 meters tall.
Difficult to put into a house, but you could shove it into the school gym fairly easily.
Circles don’t really pack that well, so the actual space used would be a little more, but you can put 100 coins in a lime that’s only 27 m long. So that both ways for a million, and stack up 1000 on each row for a billion.
That would give you a fairly loose pile of 80 ft to a side and only ~6ft deep. Totally doable for a diy. (As long as the foundation holds)
Can you just throw the money out the door? And the answer to your question would be about 1100 m3 if you somehow got 1 dollar coins packed extremely tightly but since there will be gaps with this number of coins would double it. So you are looking at around 2000m3 is roughly the size of a standard Olympic size pool.
I dont understand the question. Are there coins that each have a valuation of one billion dollars? Are the coins valued at one dollar each and there is a billion of them? This would fill an entire house easily. Am i not reading the question correctly?
Stack all coins near the door and then keep hands inside room but body outside. Then push all the stacked coins outside the door while hand remains inside
If you bring in a 10cmx10cmx10cm box, packing the coins optimally into layers yields $550 if you use dollars, $290 for quarters, $220 for dimes, $200 for 50c coins and $22 for pennies.
I would just put as many coins as I could either lift or fit in a 10x10x10 box. If they are really "billion dollar coins", how many could I possibly need?
you know.....I really don't need THAT many billions, 1 is already enough to last me 200 lifetimes. Unless you want to donate the rest to charity or something more than one is just unsubstantiated greed.
edit: wait a second, do they mean "one billion dollars worth of coins" or actually "one billion dollar coins"?
It really depends on if the "alone" part extends to outside the room. I'm pretty sure I can get one of those rare earth magnets and a one or two hundred feed of cord into a 10cm x 10cm x 10cm sized box. If I have someone I can sell the coins to for a reasonable amount outside the room I could setup my magnet and cord pretty much like a conveyer belt. If it was in Canada and using the $2 coin we - if we belted 25 coins at a time ($50) - each exchange lasting say 5 minutes working 8 hours a day we would clear $4800 a day. Do that 5 days a week for 50 weeks that's $1.2 million a year. Lucrative but terribly inefficient.
The question states "...room with 1 billion dollar coins...".
Not "...room with [many] 1-billion-dollar coins...". Still, props to those who added a creative interpretation to a hypothetical.
I go with the former. The latter is no challenge at all, since almost anyone can walk away with $20B at least.
The coins in this room where a billion 1-dollar coins are strewn about would weigh 8100 metric tonnes. That's nearly 282 standard 40-foot containers if loaded to capacity.
Now, that weight is more important than the volume in this situation. If we achieve perfect stacking, you only need 16 standard 40-foot containers for the volume occupied by the coins. But then each container would weigh more than 596 metric tonnes. You ain't loading that with a regular crane, or moving it with a regular truck.
You've all seen those giant wind turbine blades - 100 meters long. Each weighs 60 metric tonnes, and needs a special low-loader. Well, one 40-foot container with nearly 10 times that weight would crumble. The low-loader, tires and all, would buckle under the weight of just one container. And a goods train bogie will sink the rails underneath by a few centimeters if you tried getting that weight onto a single bogie.
Short answer to the original hypothetical: I'm not getting out with much if the only tool I can bring is 10cm (4 inches) or less.
So judging by the poor wording, if you pick a coin up in the room, you keep it, but it didn't say anything about once outside the room....
So let's go with each coin is worth a Dollar. You can bring a tool up to a total of 10cm ( I'm guessing wide ). I would bring a heavy duty shovel ( bit like the square snow shovels you see people clear their driveways with ) thats made out of metal 10cm wide, with a handle the normal size of a broom ( no height or depth was mentioned ). The flat surface of the scrapper will be thick enough not to break as I shovel the coins past, what we assume is the threshold of the room and into suitable containers to hold the coins able for transport. And by the wording of this, any money that leaves the room is 'yours as you have collected as much as you can'. But making sure my hands never leave the threshold when putting the coins into said containers.
Therefore I would leave one coin in the room to pick up, so I follow the rule of once it's picked up you can't put it down. Just to be annoying.
Edit: I think we have all read the coin statement wrong. Each coin is worth a Billion, so I would just pick up one coin and be set for life. Or if I was feeling greedy, I would pick up enough to fill my pockets with and be done. Might only be about 100 - 200 coins in my pocket but who cares 😁😁
The one tool I bring is my cell phone WITH a charger. I ask chat-GPT how to solve this problem and get the coins out as fast as possible.
I call my brother. . I instruct him to clear out his car... and to be on stand by.
I sit near the door. I scoop out the coins, and throw them out into the hallway. He picks them up, loads them into the car. He buys me a shovel or anything else I can use to speed this up.
He buys me food. throws it into the room. Etc. Etc.
I never break any rules, and get to stay as long as I am willing to scoop up the coins.
Okay so modern dollar coins are 2mm thick, which gives you $152.4 dollars per foot. Let's say your tool is a beer bong funnel with a hose the exact inner diameter of these coins.
Assuming you can argue that you always wear 1,242.74 miles of beer bong hose with infinite tensile strength as part of your normal outfit so it doesn't count as a tool, you can get the whole $1B, eventually, maybe.
Not going to math how long it would take to pick up this many coins, but let's assume more than a lifetime. This room sucks
If the rules is that you have to be able to carry it then what you need is a triangle of volume and strength and weight.
I think a strong fiber of canvas bag thats open mouthed as possible and a shovel with a deep mouth that easily fits in the bag. Then I shovel until I can barely walk out the room.
Whatever a coin weighs equals one billion dollars so that times idk, I think I could do over a hundred pounds if the bag had a wide enough strap. Thats my math. The shovel is my tool, and I just normally walk around with this not at all fake, perfect bag.
A durable, reinforced plastic bag that can expand beyond just 10cm. Place it on the ground to avoid it getting worn while I stuff with as much coins, then drag it outside.

Nothing is saying I can't throw coins out the door for when I leave
I mean it kind of does say that.
It says you can any coins you pick up and that you can’t put them down and pick them up later
"I" can't pick them up but my wife can and as she drove me over to this crazy experiment , she would totally be in on it.
I also choose this guys wife
Have the wife pull the car trunk to the door and just chuck them inside..
Using the same logic you could argue you can’t walk into the room with any clothes on.
It doesn’t say you can’t throw them into a massive container lined with repelling magnets that’s located out the door - so you aren’t technically “putting them down”.
Time to start eating coins
Kick them out the door?
"You can keep any coins you pick up."
I can pick them up when they’re outside, it just says I can’t go back inside once I’m done.
Fair. Question is, if you can only put them down once, do you have to take them directly to a bank?
The rules are quite sloppy. It doesn’t really matter whether or not you can pick them up and set them down, given that once you leave the room you’re done. Like, what does that even add to the challenge?
If we take it quite literally, does that extra rule mean you now can never pick up ANY coin you’ve ever picked up previously in your life ? Wouldn’t that be weird trying to collect change from a cashier and like a quarter immediately disassociates from your hand and you can’t grab it because you handled it once back in 2003?
But sure just make a deal with your friend to bank the coins for you and take a 10% cut or whatever. You don’t personally have to handle them.
Pick up every coin and put it back down. Nobody said you had to keep it in your hand.
Asking the tough questions here
Not ever, just for the duration of the experiment. Otherwise, there's no point in taking any coins.
Pick up as many as you can fit in two hands and walk out. $20-$30 billion is plenty. In fact it’s perfect because you’re not richest guy in the world famous but have eternal fu money for you and even your extended family.
Pretty sure they mean a billion one dollar coins
Maybe that’s the “trick” of this supposed question. The answer is a handful enough because they are $1 billion coins. However to me, the proper way to read this is that each coin is worth $1 billion. Otherwise it should say 1 billion $1 dollar coins.
For example switch the word coin with bills. If you said “imagine you’re in a room with 1 billion dollar bills laying on the floor”. Would you assume they were $1 bills or $1 billion dollar bills?
1$ bills, billion dollar bills doesn’t exist
Neither does a room with a billion coins but that’s besides the point. Beings this post is hypothetical.
id just take the pants off tbh. Its worth it for the amount of volume after you tie the ends. Same with shirt, just walk around in your underwear
By my guess, a pair of large boxers that have the legs tied shut can probably hold almost 2 gallons once stretched out.
A 5 gallon bucket holds around 15,000 quarters. So 2 gallons would be about 6000 quarters, or around $1,500 (rough estimate).
Personally, I'm willing to walk around nude for an extra $1,500.
I just want to see someone try to pick up some jeans full of like 5 gallons of dollar coins. lol
I used to work at a bank that had a coin counting machine, and we'd get these coin collectors that would come in every month to buy an entire box of quarters or dollar coins, go through them, and then later bring in a bucket of the loose coin that they didn't keep. Those buckets were heavy. And then the machine would sort the coins into bags, and when the bag filled up, we'd have to seal up the bag and put a new one on. Those were heavy too. The Brinks guy would bring a cart to take them away.
Why not just bring a big bag? And then you can keep your clothes on.
Joggers are ok, but a onesie is king in this situation, that and a heavy duty shopping bag that folds down to a little square when not in use.
The wording of the first sentence says 1 Billion Dollar coins. I would be set for life with just 1 coin. It's worth 1 Billion.
Reword it.. You're alone in a room with 10 Cent coins scattered on the floor.
To me this still makes sense and everything else about this game still counts 😁
It also says ‘scattered’ on the floor. A billion $1 coins would be a full Scrooge mcduck money bin (ie not scattered, rather completely full).
I do agree it reads more like each coin is worth $1 billion.
Let’s say you get a handful. Now where do you spend them?
True... Where to spend them.. maybe put them back in this room and then have even more challenging wording and instructions on how to about this experience 😁
Just ask your local newsstand if they can change a billion
Take it a step further with coveralls/jumpsuit. A few sizes too big too
I think the correct answer here would be a green lantern power ring
According to a previous post (on mobile so sorry if that formats wrong) a dollar coin has a volume of .0675 cubic inches.
Multiply that by a billion and you get 1,106 cubic meters (according to wolfram alpha). Stacking won't be perfect, so the actual volume would be more than that. You're looking at about half(ish) the volume of an Olympic swimming pool. You would need to look at how efficient randomly dropped coins pack (or the efficiency of whatever the packing system is) to come up with a more exact sense, but that gives a good sense of scale. It'd be crazy heavy, btw - about 8,000 metric tons.
EDIT: here is a post about coin packing efficiency. Pennies aren't dollar coins, but this means that our volume estimate is closer to about 80 percent of an Olympic swimming pool, with much of the volume just being air. I imagine someone has done engineering research into random coin stacking problems for e.g. vending machines and parking meters, so we could probably find a better number somewhere.
There is a 10 dollar coin thats much smaller than a dollar coin. It is made of gold, so its much denser than if it were copper or zinc. But, if the floor were covered in those, I'd be fine with just filling my pockets as much as I could hold. probably swallowing a few for good measure too. And anywhere else they would fit.
This guy drug mules!
a $10 gold coins worth about $2500 give or take , just under 17 grams of gold , personally im not greedy id be happy with just a pocket full never mind a rooms worth
But it doesn't say it's a billion dollars worth of coins
It says they are 'billion dollar coins'
Honestly I'm just filling my pockets and hands and walking out
Yeah, I parsed it as that there is a room full of dollar coins (which is what they're technically called) and that there's a billion of them.
Your case is way more lucrative lol
I thought the same thing as u/Astrochops ("A scheme to collect as many as possible! Why bother, when I'm not going to notice much difference between 1 coin and 100 coins.").
I feel like they should've used a hyphen (1 billion dollar-coins), or phrased it less ambiguously (1 billion dollars worth of coins).
Yeah, but to be fair the question in this sub doesn't make sense in that parsing. Totally agree with you, though.
No, it says there are “1 billion dollar coins”.
That is pretty ambiguous and and can be reasonably interpreted as “1 billion coins worth a dollar” or “coins worth 1 billion dollars”. TBH, wouldn’t be surprised if it wasn’t phrased that way to create engagement.
Because the premise is actually kinda lame. If it’s $1-billion coins pick one up and neither you nor your family will need to work again. If it’s $1 coins you’re not going to pick up a life changing amount.
Excluding stacking issues, how would you calculate the least negative space needed between the coins for them to fit best together and figure that into the calculation?
Vertical you can do perfectly. That's not an issue. The circular element is the problem, and you can get that to just under 91% efficient. So, you'd wind up with about 1,200 cubic meters.
That’s closest packing of circles, in a 2d plane. What about cylinders? I’m guessing it’s basically the same, just adding a stacking height limit, but you never know. There’s some weird closest stacking scenarios out there.
Only way to improve it would to somehow use vertical coins in between the plane of coins gaps.
Any set of flat coins (i.e. cylinders) would just be limited to the same limits as a 2d plane.
I find it very hard to believe that an Olympic sized swimming pool could contain a billion coins of any current size.
Not saying your math is wrong, because I have the same numbers, but damn that's hard to believe.
All the gold ever mined in humanity fits in like 3 to 4 Olympic swimming pools. All the wars, all the millions of gold miners, the millions sacrificed to the dark gods, etc. And yet we could fit it all inside a single warehouse.
They actually far less than I thought, it's at least somewhat doable
Sacagawea dollar is 8.1g, 26.5mm diameter, 2mm thickness.
A billion have a volume of 1100m3 (1.1 million litres), which would fill a room 2.5m x 21m x 21m.
I would struggle to carry much more than 50 kg.
50kg of those is $6173, with a volume of 1.1cm3 * 6173 = 6,790.3 cm³ (~6.8 litres)
I could fit those in two strong carrier bags, which would fit in a 10cm cube, so that would be my "tool".
I'd leave the remaining $999993827 for the next 161995 people.
For free money, you dig deeper than being able to carry 50kg. A young teenager can haul 50kg around.
Right? You only need to carry them out the door. Fill the bags next to the door then find the 10 seconds of strength to lift with everything you can for 2-3 steps.
Sais i can't put them down and pick them up later.
DOESN'T say i can't just toss them out the door directly into a waiting tip truck. Fill it to the brim. And drive it to the nearest bank.
Technically "I" will never pick them up again and the truck qualifies because it doesn't enter the room with me. And isn't a tool. Just my mode of transport too and from. 🤷♀️
This is the right idea, but we need to think bigger. We need to hire a team of 18-wheel tractor trailers and fill them all up. Bring a 10cm container of water and work until you are completely dehydrated/starving.
I'm just kicking them out the door
it also says once your hands leave the room youre done but nothing about the rest of you, so you could easily just kick them through the threshhold to avoid any accidental "leaving" via hands crossing the line during a throw
Yeah if you came to my bank with a truck full of coin I’m telling you to fuck right off
This question is likely to be engagement bait based on the poor wording.
If the floor has scattered upon it many coins each individually having face value USD 1,000,000,000, depending on what the state of the economy is outside, a pocketful might suffice.
If the floor has coins of face value USD 1.00, whose total quantity is 1 billion, I'd ask Reddit for someone to do the thinking for me.
It says 1 billion dollar coins, I’d assume each coin is worth 1$ USD
That is absolutely the intention behind the question. However, the way it is written opens it up to sound like they're coins that are worth $1b each.
My dumbass was initially like, “I’ll pick up two coins and leave. I don’t need more than $2 billion. That’s crazy.”
Also it doesn’t make sense to have over a million dollar coins because that is more than anyone on earth can lift at 8,100kg.
As for the question I would cheat at throw them out the dollar as it says I can keep any that I lift until I leave the room, by throwing them out I don’t have to worry about mixing them up. I would like some gloves and or a scoop of shovel or something.
"you cant put coins down and pick them back up later"
like you said it say 1billion dollar coins. not 1 billion, dollar coins
My brain is putting the parentheses in for me and reading it as (1 Billion)(Dollar Coins) instead of (1 Billion Dollar)(Coins)
Honestly doubt you could even carry a life changing amount of $1 coins.
100 pounds is like 1.7k.
Also, the tool size is vague. 10cm squared? 10cm cubed? 10 cubic centimeters? 10 cm in one direction, and no limits on the other two?
Also does the tool have to fit within those dimensions at all times? - a bag being folded up for example.
It's not worded that poorly, you know from context clues and common sense what they mean
I like how you didn’t understand the question and then just restated the purpose of posting to this subreddit
10cm bag that collapses to a compliant size but has a maximum capacity much larger. This is assuming the bag counts as "holding" it, since a tool like a trowel is technically not holding with your hands.
I'd take a 10 CM roll of fairly thick fabric, like denim, and set it up as kind of a slide out of the room. Then just pour coins in the top and let them slid out the door.
This is the way. Bring a folded up tarp, fill with coins and drag it out. This is a great way to move dirt when somewhere a wheelbarrow won’t work, just pull dirt onto the tarp and drag.
I have never seen a one billion dollar coin, so can't calculate the size. That said. I'm probably going to be content with two handfuls.
One would probably come with enough problems, I don't need two.
Most people don’t understand how much a billion dollars is. One fucking coin. I not taking any more, what’s the point. I’ve won the game I’m fucking out. Generational wealth and never worrying about the lights or water turned off. Yeah just one, that all I need.
Easy, cut one hand off and leave it in the room. Go outside rent a bulldozer and open a hole on the ground. Get back to the room and break the walls, fill that front bucket with coins then dump them at the hole. Repeat for a couple hours then go to the surgeon get your hand stitched back.
A full bucket shoud have ~10 million coins times 1 billion = 10 quitillion dollars. Depending on how any trips you can make multiply that number... or maybe just let the hand rot?
Buddy, each coin is a dollar, and there are a billion of them.
It reads "1 billion dollar coins" not "1 billion dollar in coins"
If you use 100 billion pennies, it would occupy about 2,000,000 cubic feet if optimally positioned. If you use $1 coins, it would occupy about 50,000 cubic feet if optimally positioned.
Diameter of a penny (dollar coin): 0.75 in (1.043 in)
Depth of a penny (dollar coin): 0.06 in (0.079 in)
Required volume = Ncoins * depth * diameter2
Ncoins = $1 billion/(value of coin)
Not quite optimal - you can actually pack coins tighter than you could boxes that bound them. Take a coin and surround it with six more coins in a hexagon. If you were to draw squares around each coin, the corners of those squares would overlap.
Oh, interesting! That makes sense! Thanks for sharing 😁
A 10cm folded bag/tarp can be very big once unfolded. You can spend all the time you want in there, so you don't need gizmos to pick them fast, you just need storage.
Sentence is ambiguous so I'll just fill my pockets with as many 1 billion dollar coins as possible and walk out.
As to the maths too many variables.
I'll get one of those 1m³ canvas bags that builders use for sand etc. and turn it in to a very chic hat! Once inside the room I'll simply remove the hat and take a 1m³ pile of coins with me.
I had considered a pair of pallet truck roller stakes as well as an alternative.
If it’s (coin worth $1B each), and they are a common size for coins, just grab enough to satisfy your stretch goals.
If it’s 1 Billion coins that are one dollar each, then things get harder.
If they are the modern gold color ones that would weigh 8.1 million kilograms. 182 kilograms (400lb)worth $22,446 would fit in a 36 liter medium sized backpack. An ultra light day pack should compress into the tool size required.
If you’re using “1$” Silver coins, the same weight and setup would get you $5,845 face value and trade for ~$146,140 and reasonably up to three times that.
My tool would be a parachute canopy folded to the size limit. Unfurl that fucker and start dragging coins into the chute until you can't lift it anymore.
I read this as each coin has a value of a billion dollars. I probably wouldn't even over think it. Pick is many as I can up. Probably 100 or so, and just leave with 100 billion. That's plenty of money.
But if it's normal coins like quarters and shit... There is no way you are going to be able to get anywhere near the whole billion even if you were allowed to use a wheelbarrow.
I think Most people missed the “1 billion dollar coins” part. I’ll take one for myself and a few more to donate to Wikipedia, Mozilla, United Way, and what ever other charities I can hold coins for.
Don’t have to catch them all.
Given a dollar coin weighs about 8.1g and an average person can lift about 60kg (let's go with 81kg just for the sake of it), you could carry about 10k dollars with optimal stacking/packaging. maybe if you could get a very sturdy but light fabric (parachute maybe). So the fact that there are 1 billion coins doesn't really matter, as you couldn't even get anywhere neary 1million or even 100k. not even the strongest person alive could do that.
The room contains "billion dollar coins?" if the coins are worth a billion dollars then I only need one. I'm good with that. (I know you just worded this wrong lol)
Seems pretty self evident that you just cheat and toss the coins out the door until they are all out the door. You can even push them with your feet if you like apparently. Your hands are the only thing that cannot leave the room. So just keep tossing or shoving them out whatever constitutes the way out until you have your billion or whatever and then leave.
Oddly enough I've thought of this before.
I'll take off my pants, knot them at the ankles and fill them with coins. Then just carry my pants out, no tool required.
Although a strong zip tie would leave a bit more room for coins.
How many billions could you realistically need?
Pick up 3-4 come out and give away all but one to charity, living happily ever after on the interest from one billion and then give that money away on my deathbed.
Very open to interpretation. You could be in a very small room that is unbelievably deep. In this case the size of the room is equal to the volume of a billion coins of whatever currency you pick (doesn’t specify USD, CAD, AUD, etc. lots of countries use the term dollar for their currency)
Or we could assume it’s a massive warehouse with only 1 layer of coins in which case you could roughly estimate by surface area. But the rules don’t specify how spaced out the coins are just that they are scattered on floor.
The volume can be determined solely based on the number of coins. The size of the room doesn’t matter.
Again it depends since the wording isn’t great. They simply asked what volume of space would it occupy. They didn’t specify if they are talking about the coins or the room. Poorly worded question as are most on this sub.
Don’t know why people struggle to read this problem so much. One billion objects. The objects are dollar coins.
A dollar coin is about 1.09 cubic centimeters. If you could stack them perfectly, about 1.09 billion cubic centimeters total. (About 1090 cubic meters, roughly 40% of an Olympic swimming pool)
But “scattered on the floor” suggests inefficiencies in the volume arrangement. If it’s tightly packed perfectly in a flat layer, you’d add about 10% for gaps between coins. (Perfect circle packing covers about 90.7% of a flat area).
Allowing for some overlapping coins in multiple layers, and irregular packing from “scattering “ I’d probably use more like a 33% loss of volume covered. This is purely assumption trying to guess just how disordered “scattering on the floor” looks. At this estimate, you’d fill about 50% more volume than a clean stack, yielding about 1500 cubic meters, or about 60% of an Olympic swimming pool.
So each coin is worth 1 billion dollars or there 1 billion dollars worth of 1 dollar coins scattered on the floor? 10cm tool in total size, or squared/cubed? Could I use a u-channel of any length as long as it’s 10cm in height and width and just roll coins out of the door as I’m technically not putting them down? The situation ends when just my hands leave the room? It’s all very vague! I’m not going to do the maths. Ok I’m going with the coins are worth I billion each. Fuck the 10cm tool. I’m wearing an enormously oversized and zip up boiler-suit, I’m pushing as many of the coins over to the door way as I can, I’m laying down on the floor and filling my boiler-suit up with the coins and creating a nice stable base to then place more coins on top, then when I’m ready I’ll put my hands through the doorway. After that I’m going to give all but one coin away trying to solve the world’s problems. With my remaining coin I’ll see all of my family and friends are taken care of and live on some out of the way land with hundreds of dogs.
Y'all are all misreading this.
It's 1 Billion Dollar coins, not 1 Billion DOLLAR coins.
Just grab a few and don't overthink it. Game it and be richer than anyone in history.
Wait - you could read that as each coin is worth one billion. Just pick up five or ten and leave. If the coins are only 1 dollar (there’s just a billion of them), nothing you could do within the rules makes the exercise worth it.
I would bring my cell phone into the room. I would call my family and ask them to rent a dump truck and buy several gallon buckets. I would push coins to the edge of the door and they would fill the buckets with coins and then put the coins into the dump truck. Once the dump truck is full they would bring the coins to my family’s farm, dump them, then return for another load until all the coins are removed. I would split the money evenly with them. This would likely take several days but I’m too lazy to do the math on how long it would take
Small drill. Make a hole in the door to the room and feed all the coins out through the hole. Have a few trucks and a loader outside and stock up 👍
A bucket measuring 10cm on all sides.. fill it up and fling the coins captured in the bucket outside the room... Keep doing this til your done. Then walk out the room.
Didn't say it couldn't be a magic item :).
Prepare to get retro-nerdy.
(to fit the dimensions of the prompt, they didn't say how this 10cm was measured. I'm thinking here like some kind of airline baggage check thing for entry to the room or what, so for fun I'm assuming it's a "must fit in this box" check at the door)
The wadded up Basic D&D (circa 1980s rules) version of the bag of holding. (of which OSE is a direct retro-clone of).
Bag of Holding
A normal-looking, small sack that can magically contain large objects and weights.
Size: Objects of up to 10’×5’×3’ can fit inside the bag.
Weight: Up to 10,000 coins of weight can be placed in the bag.
When full: The bag weighs 600 coins.
Now to translate that, in Basic D&D a "coin" of weight is 1/10 of a normal (avoirdupois) pound.
In later AD&D this was reduced to 1/20 of a pound. The actual weight of real world large gold coins, depending on the size, is somewhat in-between those numbers.
Sticking with the Basic D&D source material let us directly translate this coin weight into real world weight. that is 1000 customary US pounds and note that the linear dimensions ONLY refer to the size of any one object here, not the entire magical space of volume (unlike in later AD&D or later D&D). So ignore volume, only weight matters. As a side note a full Basic D&D Bag of Holding does weigh considerably more than most versions that came later, 60lbs vs 5lbs, but the brokenness of the limitless volume is great.
So, using the objectively broken version of the Bag of Holding every officially published, you can store a 1000lbs worth of real world dollar coins.
According to the Googles, the modern US Dollar coin weight only 8.1 grams exactly.
One pound = 453.592 grams
1000 pounds = 453592 grams
55999.012345679 US Dollar coins, so actually 55999 coins with the last one over just being spat out due to magic shenanigans.
So $55,999 dollars worth of modern US coins as legal tender.
Now of course if the "dollar coins" in the prompt are some kind of actual historical gold dollar coins this throws the numbers way higher, if assuming intrinsic or numismatic value.
I'm not a mather but I do have a solution to this very odd query - I'm bringing a keymaking/lockpicking tool known as a Lishi. One of it's functions is to allow you to decode the tumblers in the lock so you can copy the pattern onto a new key. Bam. Whole room is mine now! I can come and go as I please lmao
(And before anyone asks, of course I always keep a set of files and a blank key on my person... There is absolutely zero way the proprietor of this odd money room can tell me I don't and therefore, they are not additional tools 🤣)
The issue is more weight than volume or speed of picking them up. I know I can carry about 40 kg in a backpack for considerable distances, but my limit is somewhere around my own weight of 70 kg. That's $8642 dollar coins, each 8.1 g. That's just 4.6 L in volume.
I'm sure there are powerlifters that could easily handle twice that, but its a less generous giveaway than one might imagine.
Now, if the room was filled with $50 face value 1 oz gold content American Gold Eagles, the same 70 kg would permit collecting 2063 coins, with a spot value of $8,866,774, and volume of 1.94 L.
At my physical peak, I carried just over 300lbs about 50 feet (25 years ago). Currently, I know that even that amount of coins wouldn’t cover my (USA) copays for the eventual hospital ER visit for trying. So, I’m grabbing about $3000 and calling it good. 😁
Easy, the tool I'll use is a cell phone to call someone to come get the coins for me. There's also no rule about just throwing the coins out of the room and leaving afterwards.
I’d bring a 10cm cubic box. I’d also dress in layers.
Fill the box with coins. Then take off as much clothing as I’m comfortable taking off (my comfort level will increase as I get more money I’m sure), tie the clothing articles as needed and fill those.
In Canada, the largest face value coin is the Big Maple Leaf marked at $1M CAD and weighed 100KG. Its volume is about 5L. So 1000 of those coins so 5000L or about 5 cubic meters. Not that bad.
Contractor bag with the highest mil rating you could find. I'm pretty sure it could fit in a space less than 10 cm. Since there would be a barrier, you'd be able to at least walk out with 100 lbs worth. At 8 grams a coin, you're basically walking out with 5700$. If they're silver dollar coins, that's 1750$ face value and 1458 troy ounces. That's about 88,000$ worth of silver at today's prices.
I guess duct tape, as much as possible in a roll, no hollow center.
I start making stacks and covering them around with 1.5 rounds of duct tape and then the next row of coins and so on.
Eventually you end up with a giant coinc sushi made of many mini Coin sushi.
It's the only way I can think of how to be able to take out as many coins as possible in 1 go.
Eventually, I need to find a way to make a ramp out of the other coins to roll the coin sushi out of the room because there is no possible way you can lift that monster roll without any tools.
Now the question that remains is, what if I roll the whole thing out of the room but I don't leave the room? Will those coins count to my advantage and I keep making giant rolls?
Do I really need more than one or two? I'm just taking whatever my hands can take up and leaving. I'll never be able to spend it all anyways
Assuming the tool specs would allow, get a 10cm wide roll of duct tape, laying them out side to side you’d get 5,440 assuming the coins are the size of an American quarter and the industry standard length of the duct tape, which would be 100mm wide and 33 metres long, the most common result using Google. After that tie off your trouser legs and fill those puppies up. Volume obviously dependent on whether you prefer skinny jeans or parachute pants so your mileage may vary. Either way you’re leaving 99% of those coins in the room. The rules don’t say you can’t hire outside help though, you could throw them one at a time over the threshold so your hands aren’t leaving the room and you’re not picking them back up again. Might take you a while but you could get every one of them out of there.
He said once your hands leave the room. I’m taking a 10cm2 sheet of plastic and scraping the cone out of the room, being careful to never let my hands leave the room while doing so.
Amazing how many comments are litigiously dissecting the hypo w/o even playing along...I say this is a stacking game...how many stacks of coins, however denominated, can i balance long enough to get over the doorway? my 10 cm tool would be a tube of qiuck-dry water soluble glue.
Per the title. Each coin is 1 billion dollars. They mention “coins” as plural. So there can be 2 or more coins on the ground. Since they did not mention how many coins are on the ground, the default is 2. Therefore, hardly any space at all.
You're in a room with 1 billion coins, the room has one opening, a door, through which you entered.
It is not a large room
How soon before you suffocate as the coins have, by chemical reaction, consumed all the oxygen
Assuming USD “gold dollars” currently in circulation, then each coin has a thickness of 2mm and a diameter of 26.5 mm.
If made into a tower, 1 billion coins would be 2,000 kilometers tall, with a volume of 1,103 m3. To fit all that into a room you’d need a space that’s 20m on each side and 3 meters tall.
Difficult to put into a house, but you could shove it into the school gym fairly easily.
Circles don’t really pack that well, so the actual space used would be a little more, but you can put 100 coins in a lime that’s only 27 m long. So that both ways for a million, and stack up 1000 on each row for a billion.
That would give you a fairly loose pile of 80 ft to a side and only ~6ft deep. Totally doable for a diy. (As long as the foundation holds)
It says you are done when both your hands leave the room, I suppose you could chop your left hand and then take your time carrying coins to the bank
Can you just throw the money out the door? And the answer to your question would be about 1100 m3 if you somehow got 1 dollar coins packed extremely tightly but since there will be gaps with this number of coins would double it. So you are looking at around 2000m3 is roughly the size of a standard Olympic size pool.
I dont understand the question. Are there coins that each have a valuation of one billion dollars? Are the coins valued at one dollar each and there is a billion of them? This would fill an entire house easily. Am i not reading the question correctly?
Not the math
Stack all coins near the door and then keep hands inside room but body outside. Then push all the stacked coins outside the door while hand remains inside
If you bring in a 10cmx10cmx10cm box, packing the coins optimally into layers yields $550 if you use dollars, $290 for quarters, $220 for dimes, $200 for 50c coins and $22 for pennies.
Sources: 1. https://en.wikipedia.org/wiki/Circle_packing 2. Piece of paper and scientific calculator I had on my desk
EDIT: Didn’t read the title, my bad
I would just put as many coins as I could either lift or fit in a 10x10x10 box. If they are really "billion dollar coins", how many could I possibly need?
Pretty sure after the first few dozen coins you would crash the economy.
But honestly I don't see the problem since just a single hand can probably hold like ten or twenty coins, I think 20 billion is enough to live on.
you know.....I really don't need THAT many billions, 1 is already enough to last me 200 lifetimes. Unless you want to donate the rest to charity or something more than one is just unsubstantiated greed.
edit: wait a second, do they mean "one billion dollars worth of coins" or actually "one billion dollar coins"?
Metal paint scraper or similar and sweep them out the door.
Bonus points, and coins, if you brought a partner to move them out of doorway or there's a staircase or drop off outside the door.
I'll just move into the room and my tool will be a cell phone. I'll hire bankers and workers to come clean up everything until I get everything.
It really depends on if the "alone" part extends to outside the room. I'm pretty sure I can get one of those rare earth magnets and a one or two hundred feed of cord into a 10cm x 10cm x 10cm sized box. If I have someone I can sell the coins to for a reasonable amount outside the room I could setup my magnet and cord pretty much like a conveyer belt. If it was in Canada and using the $2 coin we - if we belted 25 coins at a time ($50) - each exchange lasting say 5 minutes working 8 hours a day we would clear $4800 a day. Do that 5 days a week for 50 weeks that's $1.2 million a year. Lucrative but terribly inefficient.
The question states "...room with 1 billion dollar coins...".
Not "...room with [many] 1-billion-dollar coins...". Still, props to those who added a creative interpretation to a hypothetical.
I go with the former. The latter is no challenge at all, since almost anyone can walk away with $20B at least.
The coins in this room where a billion 1-dollar coins are strewn about would weigh 8100 metric tonnes. That's nearly 282 standard 40-foot containers if loaded to capacity.
Now, that weight is more important than the volume in this situation. If we achieve perfect stacking, you only need 16 standard 40-foot containers for the volume occupied by the coins. But then each container would weigh more than 596 metric tonnes. You ain't loading that with a regular crane, or moving it with a regular truck.
You've all seen those giant wind turbine blades - 100 meters long. Each weighs 60 metric tonnes, and needs a special low-loader. Well, one 40-foot container with nearly 10 times that weight would crumble. The low-loader, tires and all, would buckle under the weight of just one container. And a goods train bogie will sink the rails underneath by a few centimeters if you tried getting that weight onto a single bogie.
Short answer to the original hypothetical: I'm not getting out with much if the only tool I can bring is 10cm (4 inches) or less.
So judging by the poor wording, if you pick a coin up in the room, you keep it, but it didn't say anything about once outside the room....
So let's go with each coin is worth a Dollar. You can bring a tool up to a total of 10cm ( I'm guessing wide ). I would bring a heavy duty shovel ( bit like the square snow shovels you see people clear their driveways with ) thats made out of metal 10cm wide, with a handle the normal size of a broom ( no height or depth was mentioned ). The flat surface of the scrapper will be thick enough not to break as I shovel the coins past, what we assume is the threshold of the room and into suitable containers to hold the coins able for transport. And by the wording of this, any money that leaves the room is 'yours as you have collected as much as you can'. But making sure my hands never leave the threshold when putting the coins into said containers.
Therefore I would leave one coin in the room to pick up, so I follow the rule of once it's picked up you can't put it down. Just to be annoying.
Edit: I think we have all read the coin statement wrong. Each coin is worth a Billion, so I would just pick up one coin and be set for life. Or if I was feeling greedy, I would pick up enough to fill my pockets with and be done. Might only be about 100 - 200 coins in my pocket but who cares 😁😁
The one tool I bring is my cell phone WITH a charger. I ask chat-GPT how to solve this problem and get the coins out as fast as possible.
I call my brother. . I instruct him to clear out his car... and to be on stand by.
I sit near the door. I scoop out the coins, and throw them out into the hallway. He picks them up, loads them into the car. He buys me a shovel or anything else I can use to speed this up.
He buys me food. throws it into the room. Etc. Etc.
I never break any rules, and get to stay as long as I am willing to scoop up the coins.
I never leave.
Lol
What's the point in having a billion coins worth a dollar? No matter what tool you bring you wouldn't get anywhere close to taking them all.
Okay so modern dollar coins are 2mm thick, which gives you $152.4 dollars per foot. Let's say your tool is a beer bong funnel with a hose the exact inner diameter of these coins.
Assuming you can argue that you always wear 1,242.74 miles of beer bong hose with infinite tensile strength as part of your normal outfit so it doesn't count as a tool, you can get the whole $1B, eventually, maybe.
Not going to math how long it would take to pick up this many coins, but let's assume more than a lifetime. This room sucks
If the rules is that you have to be able to carry it then what you need is a triangle of volume and strength and weight.
I think a strong fiber of canvas bag thats open mouthed as possible and a shovel with a deep mouth that easily fits in the bag. Then I shovel until I can barely walk out the room.
Whatever a coin weighs equals one billion dollars so that times idk, I think I could do over a hundred pounds if the bag had a wide enough strap. Thats my math. The shovel is my tool, and I just normally walk around with this not at all fake, perfect bag.
A durable, reinforced plastic bag that can expand beyond just 10cm. Place it on the ground to avoid it getting worn while I stuff with as much coins, then drag it outside.
superglue.
take off pants, super glue the feet opening together, fill pants with coins.
Repeat with blouse, superglue hand opening and neck opening, and fill with coins.
