Web... so it's a triangular prism. No Curves! A prism is a polyhedron, which means all faces are flat! No curved sides. For example, a cylinder is not a prism, because it has curved sides. Bases The ends of a prism are parallel and each one is called a base. Sides The side faces of a prism are parallelograms WebJan 19, 2013 · A pentagonal prism has only 7 faces. Each of the five lateral faces is perpendicular to the two bases: that makes 10 pairs of mutually perpendicular faces. In general, the lateral faces are not perpendicular, but four of them may be perpendicular to one or more of its neighbors - at most 4 more pairs. Still not 25!
