Question

can anyone help me please!!??

For each polyhedron, use Euler’s Formula to find the missing number.
4. Faces: 9 Edges: Vertices: 14

6. Faces: Edges: 24 Vertices: 16

Answer 1

Isn't the formula

Faces + Vertices = Edges + 2

which can be written as

Faces + Vertices - 2 = Edges

now substitute the information to find the solution

Answer 2

so then number 4 would be 21?

Answer 3

Answer 4

would the awnser be 10

Answer 5

question 6 is 10
