According to this picture/fact, all gold ever mined is able to fit in a 20x20x20 meter cube.

All of the gold mined in the history of the world would fit into a 20x20x20 meter cube.

Is there any evidence of this, as this seems like very very little gold?

  • The factoid I am familiar with says that all the gold ever mined would fit into a single Olympic size swimming pool. – Wad Cheber Jun 6 '15 at 23:44

    A cubic volume always sounds like less than it is. To think about it a another way; a 1 meter diameter "wire" of gold would stretch for over 10km – Richard Tingle Jun 7 '15 at 10:41

    Saying the length of each dimension is probably what makes it seem smaller: 20 by 20 by 20 meters sounds like less than 8000 cubic meters. – Peter Olson Jun 9 '15 at 1:17

From Carlin: Where the Train Stops ... and the Gold Rush Begins, InfoMine

Official estimates indicate that total world gold production since the beginning of civilization has been 4.97 billion troy ounces.

4.97 billion troy ounces is 155 million kg.

The density of gold is 19,300 kg/m3.

155 million kg of gold only requires 8000 m3. That is 20m x 20m x 20m.

That's as of about 2008. A Sklivvz's answer shows, by 2012, the cube had grown to 21m x 21m x 21m.


Here's how big that is:

According to Wikipedia and the World Gold Council,

A total of 174,100 tonnes of gold have been mined in human history, according to GFMS as of 2012.This is roughly equivalent to 5.6 billion troy ounces or, in terms of volume, about 9020 m3, or a cube 21 m on a side.

    Apparently we've mined an extra 1000 m³ of gold in the last four years... – Joe Jun 5 '15 at 16:57

    @Joe or they re-estimated the past digging... – Sklivvz Jun 8 '15 at 17:07
