Use Euler's Formula to find the missing number

Question

Faces:27
Vertices:20
(1 point)
Number of Edges :

Answer 1

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.
