Question

Use Euler’s Formula to find the missing number. Faces: 15 Vertices: 11 Edges? a. 27 b. 24 c. 25 d. 23

Answer 1

Euler's formula for Vertices, Edges and faces is V-E+F = 2

Replace the letters with the given information and solve for the missing one.

From the problem V ( Vertices) = 11 and F (faces) = 15.

11 - E + 15 = 2

11 + 15 = 26

26 - E = 2

E = 26-2

E = 24

The answer is b. 24
