1. Use Euler's formula to find the missing number. Vertices: 18 Edges: 22 Faces: ? (1 point) Responses 4 4 5 5 6 6 8
The formula is: V - E + F = 2, where V is the number of vertices, E is the number of edges, and F is the number of faces.
Substitute the given values: 18 - 22 + F = 2
Rearrange the formula: F = 22 - 18 + 2
Calculate: F = 4 + 2
Therefore, the missing number of faces is 6.
