> that be 312lb(142kg)...not easy to disguise

I think that’s a cube about 8 inches (~19cm) per side.

Tough to disguise if carrying it solo, but maybe not so tough to hide in a cargo plane somewhat inconspicuously.

The pictures in the article show them as being shaped like machine parts.

Yeah, gold is not quite twice as dense as lead. It's weirdly heavy, but few people handle it in large enough quantities to notice.

Uncle is a goldsmith. I once held a decently sized bar of gold (I'd say 30x10x2cm) in my hand and you're absolutely right, it really is weirdly heavy in a way you'd not expect.

If anyone wants to try it, Sovereign Hill in Ballarat, Australia does daily forgings of a gold bar. They melt it down, pour into a mold, let it cool for a minute or two, and then guests can hold it. I've got a picture of my kids almost dropping ~$300k onto the floor.

Seems to fit in 1 truck:

  10,000,000 / 2,000 = 5,000 ounces
  1 ounce = 28.35 grams
  5,000 * 28.35 = 141,750 grams
  1 cm^3 = 19.3 grams gold
  141,750 / 19.3 = 7,345 cm^3 gold
  % Truck bed volume: .4%
