Prism – a polyhedron with two congruent faces that are polygons containedin parallel planes. These two faces are called the bases. The other facesare called lateral faces and are shaped like parallelograms.

Exploring Three-Dimensional Figures

Prisms are named by the shape of their bases. A regular prism is a cube.
