Question 302449
Try to make a cylinder out of a piece of 
paper by taping an opposite pair of edges
together. You can see that it has an inside 
and an outside surface, so
surfaces = 2
The only edges are the circular edge at one end
and the circular edge at the other end, so
edges = 2
Vertices are where 2 edges meet, and the edges
don't meet, so
vertices = 0
