well, F+V = E+2
Surely you can solve to find F, the number of faces ...
F is what I'm trying to figure out.
Answered by oobleck
well geez - plug in your numbers!
F+22 = 34+2
<u>Now</u> can you find F?

Instead of being rude about it tell them nicely.

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

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
