Question

Define Eulerts relation between the number of faces,
number of edges and number of vertices for various 3-
dimensional figures​

Answer 1

answer:

This page lists proofs of the Euler formula: for any convex polyhedron, the number of vertices and faces together is exactly two more than the number of edges. Symbolically V−E+F=2. For instance, a tetrahedron has four vertices, four faces, and six edges; 4-6+4=2.
