How do you compare the number of faces to the number of vertices's in a cube?

The number of faces is 6, the number of vertices (not vertices's) is 8.


Does a cylinder have any vertices?

anything with angles does have vertices * * * * * The circular base of a cylinder meets the curved surface at an angle of 90 degrees. So there are an infinite number of angles, but not a vertex in sight. Something wrong with your statement, perhaps!

How many eadges does a pyramid have?

It depends on the base of the pyramid. To find it, add the number of edges of the vertices is of the base to its number of edges. Example: for a square pyramid, there is 4 vertices and 4 edges in the base. The Edges of the pyramid is then 4+4 which equals 8.
