Euler's polyhedron formula

That is what I was thinking, but how do i do it because I am missing the vertices...

V - E + F = v- 33 + 20= ? =2

would it be 51

brush up on your algebra/arithmetic ...

V - 33 + 20 = 2

V - 13 = 2

V = 15

Yeah, I know I missed a step. Thanks I figured it out as you posted. Thanks!!!
