Question

Please help geometry

Answer 1

10

Explanation:

There are 6 faces and 6 vertices.

The formula is F + V = E + 2.

So,

6 + 6 = E + 2

12 = E + 2

E + 2 = 12

E = 10

There are 10 edges.

Answer 2

E = 10

Explanation:

Faces = F = 6

Vertices = V = 6

Edges = E = ?

F + V = E + 2

6 + 6 = E + 2

12 = E + 2

E = 12 - 2

E = 10
