If you are asking this then you must be crazy because it is so easy but for those crazy people out there it is 4.

cans are cylinders which consist of circles so there are no edges* * * * *A cylinder has two circular edges - where the curved surface meets the plane faces that form the ends (or bases).

118 edges

A square pyramid has 8 edges and 5 vertices. The base is a square with four edges and vertices. The sides are made of 4 triangles each sharing an edge and vertex.

An octagonal prism has 10 faces, 24 edges and 24 edges(!)Oh, and in case you are interested, 16 vertices.
