A pyramid and a prism share the same base. The prism has 99 edges. How many faces does the pyramid have?

I tried 66... supposedly, that's not the answer.

Edges of a prism =

3 times the base edges

So

3 * base edges = 99 divide both sides by 3

base edges = 33 = edges of pyramid's base

The pyramid will have the same number of faces as base edges = 33
