A cube is indicated by an edge, a face, and two vertices of a cube. If e, f, and v denote the number of edges, faces, and vertices, respectively, of a cube, which of the following is true?
(A) e + f = v + 8
(B) e + f = v + 6
(C) e + f = 20 - v
(D) e - f = v - 2
(E) e – f = v/2
I do know the following stats about cube:
e=24
f=6
