Gold fact of the day

…the world produces a cube of gold that is about 4.3 meters (about 14
feet) on each side every year. In other words, all of the gold produced
worldwide in one year could just about fit in the average person’s
living room!

The total amount of gold, ever produced by mankind, is estimated to fill only one-third of the Washington Monument.  Here are the calculations, including an estimate for the even more scarce platinum.  Hat tip to Jason Kottke.
