v= volume
h= height
a= area of the base
s= length of the base along the ground.

Okay, imagine an egyptian pyramid. Square base, four sides. The volume should be v=(h*a)/2

Let's then say that the height is the same as the side of the base so a=s*s and h=s gives v=(s*s*s)/2

From your link we know that 655 000 skulls have a volume of 13100 cubic metres. That gives 13100=(s*s*s)/2 which gives 26200=s*s*s which gives that, the square root of three of 26200=s

I think. But I have lost my calculator so somebody else have to calculate s.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
