Question

ernest has a job helping a jewler. he had the assignment of counting faces, vertices and edges on the emeralds. on the first emerald enrest hcounted 6 faces and 6 vertices. he quickly realized he didnt have to count the edges. how many edges were there?

Answer 1

This can be easily calculated using Eular's Formula

V + F - E =2

Answer 2

Here
V = number of vertices
F = number of faces and
E = number of edges

Answer 3

In your case,
F = 6
V = 6

Substituting them in Eular's formula, we get

6 + 6 - E = 2
12 - E = 2
12 - 2 = E
10 = E

Hope this is clear??? :D
