Examples of polyhedrons include a cube, prism, or pyramid. Non-polyhedrons are cones, spheres, and cylinders because they have sides that are not polygons. A prism is a polyhedron with two congruent bases, in parallel planes, and the lateral sides are rectangles. ... All prisms and pyramids are named by their bases.

Is a polyhedra a prism?

A prism is named for the shape of its bases. ... A pyramid is a type of polyhedron that has one special face called the base.
