Question

Use Euler’s Formula to find the missing number. Faces: 8 Edges: _____ Vertices: 6

Answer 1

The number of edges is
`E=12`

Explanation:

we know that

The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

so

`V- E + F = 2`

In this problem we have

`F=8, V=6`

substitute and solve for E

`6- E + 8 = 2`

`E=6 + 8 -2=12`
