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.

Yes I did that and got 11... Yet a lot of my friends who did the homework before me are saying the correct answer is 9? I'm really confused if they are or wrong or I'm wrong.
