(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What is the number of edges of a convex polytope with n vertices all of whose faces are triangles.

2. Relevant equations

# of faces + #of vertecies = # of edges + 2

3. The attempt at a solution

My reasoning is as follows:

n/3 + n = # of edges + 2

4n/3 - 2 = #of edges

This doesn't seem right though. Am I using the correct formula?
