Pyramidal Frustum A pyramidal frustum (or truncated pyramid) is a solid which can be created by chopping off the top of a pyramid. The bottom face and the top face of the frustum are in parallel. The sides are trapezoids and meet at a common point. The surface S_s of the sides of the truncated pyramid can be calculated as S_s = 0.5(p_b+p_t)s, with p_b and p_t as the perimeters of the bottom and the top face, and s as the slant height. The total surface S is given by S = S_s + A_b + A_t The volumn V of the pyramidal frustum is
