Use Euler's formula to find the missing number.
Vertices: 18
Edges: 22
Faces: ?
(1 point)
To find the missing number of faces, we can use Euler's formula, which states that for any polyhedron, the number of vertices (V), edges (E), and faces (F) are related by the equation:
V - E + F = 2
In this case, we know that V = 18 and E = 22. Plugging these values into the formula, we can solve for F:
18 - 22 + F = 2
-4 + F = 2
F = 2 + 4
F = 6
Therefore, the missing number of faces is 6.
