vertices 14 edges 16 faces ? use Euler's formula.

Question

1.24
2.25
3.23
4.27

Answer 1

The correct answer is 3. 23

Using Euler's formula (V - E + F = 2), where V = number of vertices, E = number of edges, and F = number of faces:

14 - 16 + F = 2
F = 16 - 14 + 2
F = 4 + 2
F = 6

Therefore, the number of faces is 23.
