Look at a polyhedron, for instance, the cube or the icosahedron above, count the number of vertices it has, and name this number V. The cube has 8 vertices, so V = 8. Next, count and name this number E for the number of edges that the polyhedron has. There are 12 edges in the cube, so E = 12 in the case of the cube. theoretical framework on perception
