## Is a cube a polyhedron

The Platonic solids, also called the regular solids or regular polyhedra, are convex polyhedra with equivalent faces composed of congruent convex regular polygons.

_{Did you know?Let v, e, and f be the numbers of vertices, edges and faces of a polyhedron. For example, if the polyhedron is a cube then v = 8, e = 12 and f = 6. Problem #8 Make a table of the values for the polyhedra shown above, as well as the ones you have built. What do you notice? You should observe that v e + f = 2 for all these polyhedra. Regular icosahedron. In geometry, a regular icosahedron ( / ˌaɪkɒsəˈhiːdrən, - kə -, - koʊ -/ or / aɪˌkɒsəˈhiːdrən / [1]) is a convex polyhedron with 20 faces, 30 edges and 12 vertices.
