Is a cube a polyhedron
The cube is a regular polyhedron (also known as a Platonic solid) because each face is an identical regular polygon and each vertex joins an equal number of faces. There are exactly four other regular polyhedra: the tetrahedron, octahedron, dodecahedron, and icosahedron with 4, 8, 12 and 20 faces respectively.The cuboctahedron, also called the heptaparallelohedron or dymaxion (the latter according to Buckminster Fuller; Rawles 1997), is the Archimedean solid with faces 8 {3}+6 {4}. It is one of the two convex quasiregular polyhedra. It is also the uniform polyhedron with Maeder index 7 (Maeder 1997), Wenninger index 11 (Wenninger 1989), Coxeter ...knew about regular polyhedra, as evidenced by his inclusion of five regular polyhedra in his work “the Timaeus”. He associated the cube with earth, the tetrahedron with fire, the octahedron with air, and the icosahedron with water. The model for the whole universe was the dodecahedron. These became known as the Platonic solids (for Plato). The
