Is a cube a polyhedron

The Greek words poly, which means numerous, and hedron, which means surface, combine to form the word “polyhedron.” The number of faces of a polyhedron determines what type it is. A polyhedron is a closed solid with plane faces enclosing it. A polyhedron’s faces are all polygons. A cube is a polyhedron with six right-angled polygonal edges.
