Answer:

V = 8

Step-by-step explanation:

we know that

The Euler's formula state that: In a polyhedron, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

V - E + F = 2

in this problem  we have

V=?\\E=12\\F=6

substitute the given values

V - 12 + 6 = 2

solve for V

Combine like terms left side

V - 6 = 2

Adds 6 both sides

V - 6+6 = 2+6

V = 8
