In geometry, a face is any of the polygons that make up the boundary of a polyhedron. For example, a cube has six faces, each of which is a square. The polygons that bound higher-dimensional polytopes are also called faces.
In regular polyhedra (the Platonic solids), all faces are congruent regular polygons.
