Question

Using Euler's Formula, given Edges = 12, Vertices = 8, how many Faces?

A.10

B.8

C.6

D.4

Answer 1

The short answer is c

Answer 2

C

Explanation:

Euler's formula for polyhedra states that

F + V - E = 2 ( F is faces, V vertices and E edges ), thus

F + 8 - 12 = 2, that is

F - 4 = 2 ( add 4 to both sides )

F = 6

The number of faces is 6
