Question

Use Euler’s formula to find the missing number. Vertices: 22 Edges: 34

a 10
b 12
c 14
d 16

Answer 1

well, F+V = E+2
Surely you can solve to find F, the number of faces ...

Answer 2

F is what I'm trying to figure out.

Answer 3

well geez - plug in your numbers!
F+22 = 34+2
<u>Now</u> can you find F?

Answer 4

Instead of being rude about it tell them nicely.

Anyway, the answer for anyone else looking is C. 14! Hope it helps.

Answer 5

Yeah well instead of letting them plain out cheat and be dumb just tell them the formula so they know how to do it next time, even I figured it out.
*For those of you wondering...*
use @oobleck 's formula
F+V = E+2
fill it in
F+22 = 34 +2
F+22 = 36
36-22=14
F=14
