"Will all the gold in the world fill 2 Olympic sized swimming pools?"
http://en.wikipedia.org/wiki/Gold
Density of gold: 19.30 g·cm-3
http://en.wikipedia.org/wiki/Kilogram_per_cubic_metre
1 g/cm3 equals 1000 kg/m3
thus:
19,300 kilos per cubic meter for gold

1 kilogram = 32.1507466 troy ounce
620,509 troy oz. per cubic meter
1 tonne = 32,150.7466 troy ounce
19.3 tonnes per cubic meter, acts to check and prove the "kilo per oz." and "tonne per oz." math is correct.
19,300 kilos = 19.3 metric tonnes per cubic meter.
155,000 tonnes of gold mined in all of human history
divided by 19.3 tonnes per cubic meter,
equals 8031 cubic meters!
Volume of an Olympic Swimming Pool?
http://hypertextbook.com/facts/2005/...yGilbert.shtml
25 meters by 50 meters by 2-3 meters deep = 25 x 50 x 2.5 = 3125 cubic meters
8031 cubic meters / 3125 cubic meters = 2.57 pools
Thus, all the gold in all the world, ever mined in all of human history, will fill 2.57 Olympic Sized swimming pools.
Since the depth of an Olympic Swimming pool can be deeper, and since the 2-3 meter depth is a minimum, all the gold in all the world would easily fit into two slightly deeper than normal, Olympic Sized Swimming pools.
