Is a cube a polyhedron
There are five types of convex regular polyhedra--the regular tetrahedron, cube, regular octahedron, regular dodecahedron, and regular icosahedron. Since the numbers of faces of the regular polyhedra are 4, 6, 8, 12, and 20, respectively, the answer is. 4 + 6 + 8 + 12 + 20 = 50.\ _\square 4+ 6+8+12+20 = 50. .A cube is a solid figure called a polyhedron. A polyhedron is a solid figure with all flat faces. So a cone would be a solid figure but not a polyhedron becasue it has a curve and does not have all flat faces.
