polyhedra

Cubes and pyramids

Polyhedra is the plural of polyhedron—a three-dimensional solid bounded by flat polygonal faces.

Cubes, pyramids, and dodecahedrons are polyhedra.

The term appears in geometry, architecture, and crystallography: The artist's sculptures featured complex polyhedra.

Regular polyhedra have identical faces; irregular ones do not.
