Use Euler’s formula to find the missing number
Faces: 27
Vertices: 20
How many edges?
To find the missing number (number of edges), we can use Euler's formula:
F + V - E = 2
Given:
F = 27 (number of faces)
V = 20 (number of vertices)
Plugging in the values:
27 + 20 - E = 2
47 - E = 2
-E = 2 - 47
-E = -45
E = 45
Therefore, the number of edges in this figure is 45.
