Use Euler's Formula to find the missing number Faces:27 Vertices:20 (1 point)
To use Euler's Formula, we plug in the values for the faces, vertices, and the missing number:
F - V + E = 2
27 - 20 + E = 2
Solve for E:
27 - 20 + E = 2
7 + E = 2
E = 2 - 7
E = -5
Therefore, the missing number of edges is 5.
