Using Euler's formula, how many edges does a polyhedron with 8
faces and 12 vertices have?
[?] edges
Euler's Formula: F + V = E + 2

Euler's Formula states that

F+V=E+2

We are given a polyhedron with 8 faces and 12 vertices.

Let's plug these numbers into the formula and then solve for E:

8+12=E+2

20=E+2

20-2=E

18=E

Therefore, the given polyhedron has 18 edges.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
