Question

Euler formula for dodecahedron​

Answer 1

Answer:

V-E+ F = 2; or, in words: the number of vertices, minus the number of edges, plus the number of faces, is equal to two. which is what Euler's formula tells us it should be. If we now look at the icosahedron, we find that V = 12, E = 30 and F = 20.
