Use Euler's Formula to find the number of vertices in a polyhedron with 6 square faces and 12 edges.

A. 6

B. 8

C. 10

D. 12

B

Step-by-step explanation:

Euler's formula for polyhedra states that

F + V - E = 2

(F is faces, V is vertices and E is edges)

Here F = 6 and E = 12, thus

6 + V - 12 = 2, that is

V - 6 = 2 (add 6 to both sides)

V = 8 → B
