All the gold in the world could fit into a cube with sides 67ft/20m long

          I couldn't think of a shorter title, so there you have it. I found that BBC News does this thing called 10 things we didn't know last week that is a list of 10 newly discovered facts. The 9th fact about gold (above the ground) just happened to be featured on a twitter post and it had a lot of math potential. We can answer questions like: How much does all the gold in the world cost? How much does it weigh? How many 53ft trailer trucks would it take to carry it using the maximum amount of space? How many solid gold bowling balls could you make? How heavy would each bowling ball be? How many Olympic weight lifting gold medalists would it take to lift it? How many more questions can you think of? If anyone actually wants to do any of these, here's some info: 1 pound of gold is 1.436 cubic inches. A pound of gold costs about $22,630.75 today, but it changes daily. A 53ft trailer truck has 4,006.4 cubic feet of storage space. A bowling ball is about 331.878 cubic inches. And finally, the Olympic record for weightlifting is 472kg which is 1040.288lb. Check back soon for the answer!
