A prism is a polyhedron with two parallel

A prism is a polyhedron with two parallel faces called bases. The other faces are always parallelograms. The prism is named by the shape of its base. A polyhedron is simply a three-dimensional solid which consists of a collection of polygons usually joined at their edges.
