If you're looking a 20 x 20 x 20 meters of gold (i.e. 8000 cubic meters, not a 20m3 cube) then that's more like 154,000 metric tons. Which Wolfram Alpha helpfully confirms is approximately equal to the mass of all gold ever mined. There is some contention about this value, the World Gold Council posit 197,576 metric tons (and up to 3000 additional tonnes per year) [1], USGS suggest a cube with 28 meter sides, or 244,000 metric tons [2]. 400,000 kg probably comes from 20 cubic meters of gold (386,000 kg).
