If an octahedron has 12 edges, how many vertices does it have?

F + V = E + 2

• V = 5

• V = 6

• V = 7

• V = 8

If a cube has 8 vertices, how many edges does it have?

F + V = E + 2

• E = 8

• E = 10

• E = 12

• E = 14

If a dodecahedron has 30 edges, how many vertices does it have?

F + V = E + 2

• V = 14

• V = 16

• V = 18

• V = 20
