Use Euler's Formula to find the missing number
Faces:27
Vertices:20
(1 point)
Number of Edges :
The number of edges can be calculated using Euler's Formula:
F - E + V = 2
Given:
F = 27
V = 20
Substitute the given values into the formula:
27 - E + 20 = 2
Simplify:
47 - E = 2
Subtract 47 from both sides:
-E = -45
Divide by -1:
E = 45
Therefore, the number of edges is 45.
