Question

Use Euler's formula to find the missing number.
Vertices: 13
Edges: 28
Faces:?
(1 point)
• 17
• 16
• 18
• 20

Answer 1

To use Euler's formula, we can apply the formula:

Vertices + Faces = Edges + 2

Given that Vertices = 13 and Edges = 28, we can substitute these values into the formula:

13 + Faces = 28 + 2

Simplifying the equation, we have:

Faces = 28 + 2 - 13

Faces = 30 - 13

Faces = 17

Therefore, the missing number of Faces is 17.
