prism - a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms. polyhedron - a solid figure bounded by plane polygons or faces. parallelepiped, parallelepipedon, parallelopiped, parallelopipedon - a prism whose bases are parallelograms.
(Technically, when the sides are rectangles, the shape is known as a right prism, indicating that the lateral faces meet the sides of the base at right angles. In this lesson, when we use the term prism, we mean a right prism. But there are other types of prisms, too.) A prism is described by the shape of its base. For instance, a rectangular prism has bases that are rectangles, and a pentagonal prism has bases that are pentagons.
