Okay, but you’ve never seen a 10’ pile of clothes at a donation center, or a 10’ pile of trash?
Think about it, assuming average height is 5’ (short, I know) and a person is roughly 1 1/2’ wide, the bottom later of a perfectly laid body pile is only going to be 12 people. The next layers will be smaller because it’s less stable. You could easily have, say, thirty dead to make a 10’ pile. In a prison of that size with those conditions, that’s an easy number. 10’ isn’t a mass grave in WW2 or Syria.
