theres some equation that aids in this that i can never really recall.  
something like v+f = 2+e

anonymous · Answer

Okay, ill try that

google says its good,  so essentially its asking you if  v+f-e = 2

anonymous · Answer

Yes. That means polyhedron 3 is incorrect. Can you double check that for me??
