# Is all gold ever mined able to fit in a 20x20x20 meter cube?

According to this picture/fact, all gold ever mined is able to fit in 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
• All the gold in the world would fit in a singularity – Paul Jun 8 '15 at 2:22
• 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

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

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:

• It seems like a lot when you say 155 million kilograms, but a 20m^3 cube doesn't sound very large. Thanks however! – user1622951 Jun 4 '15 at 22:12
• @user1622951 It's not 20 m^3 it's 20^3 m^3 i.e. 8000 m^3! – Bakuriu Jun 5 '15 at 7:31
• 20m^3 is a physical measure, @steveives, and it's the wrong value at that. (20m)^3 != 20(m^3) – Sklivvz Jun 5 '15 at 10:11
• Has it grown that much, or is Sklivvz answer based on a different estimate? 155kt to 174kt in just 4 years is quite a lot. – CodesInChaos Jun 7 '15 at 9:25

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
• Or it got warmer. – amaca Jun 12 '15 at 8:08
