it's not F+VE = 2?

Ok here is my question. First, how do I thank you for your help? Second, what is the sum of the number of vertice, edges, ad faces of a dodecahedron?

Ok well the prefix "dodeca" is telling 12, so it's a polyhedron with 12 faces (F)

Right. But what about the other 2 parts?

Well you can try counting how many vertices there would be, in this case there are 20

I'm sure there is a systematic way :(
Thanks for your help though

From there you can use the formula to find out how many edges you have
F+VE = 2
12+20E=2
32E=2
30 = E
