Loads of copper weighing 45,000lbs are 1 pallet wide, 10 pallets down the middle of the trailer, and no more than a foot tall.
Gold is heavier than copper.
A pallet is about 4x4 isn’t it?
Still, to imagine that something a bit less than 3x3x3 weighs 18 tons make me want to check my math.
Like I said, I have a wooden file cabinet that is almost exactly those dimensions sitting next to this desk. Imagining that weighing 18 tons is hard to do.
