    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)

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

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