If you took all of the air on earth and compacted it into a cubic foot how much would it weigh?

Answer 1

regardless of what size or shape you compacted it to, it would weigh approximately 5.27 X 10^18 kg (5,270,000,000,000,000,000 kg)

Answer 2

OK, this is a trick question because it depends on your requirements and what is being supported. The straight out answer is 62.4 lbs per cubic foot. That would be the case where you put a platform on the tubes and want to know how much the platform and its contents can weigh before it sinks down to water level. Another way of looking at it is the case where the load that it is supporting is suspended from the tubes, like an anchor. Unless the object suspended from the tubes is a point mass, it will have volume and some buoyancy of its own. Even an anvil will weigh less underwater than it does on dry land, so the answer two the second part is "Depends on the nature of what you're supporting." A couple of inner tubes will easily support a pair of 200 lb individuals in the water since their density is close to the density of the water.

Answer 3

I don't think you could compact that much air into a cubic foot. It would be impossible, obviously, but Im guessing it'd way millions of tons.

Answer 4

thats a good question - or how much would other things weigh wen there was no air bouyancy?

it would weigh differently depending how close to earth you held it, but more than its total weight when spread out over miles

Answer 5

Its weight (or mass) will be same but its density will be enormous, but will be less than that of a black hole.
