Pyramid Volume Calculator
Like a cone, a pyramid occupies one third of the prism around it. The slant height is measured from the middle of a base edge to the apex and drives the triangular faces; the lateral edge runs from a base corner to the apex and is the longer of the two, since it cuts across the base diagonally.
