Answer 4

But hows that work when I don't have the number of vertices? I put it in as x and solve the equation?

Answer 5

So for any convex polyhedron, the relationship between the Edges, Vertices, and Faces is given by:\[\bf F+V-E=2\]Substitute for the already given number of faces and number of edges and solve for the number of vertices:\[\bf 12+V-20=2 \implies V=?\]

Answer 6

Oh, ok! I'll so that right now

Answer 7

*do

Answer 8

And you understand what convex means right?

Answer 9

I got 10 vertices =D Isn't convex smaller then 180? Or is that 360?
