Strangely enough, a 6 sided hexagon has 6 sides! In fact, if it did not have 6 sides, it would not be a hexagon. A hexagon also has 6 vertices. It is a two dimensional shape and so does not have faces, although some people do consider it to have one face.
A solid shape with 6 faces, yes. A plane shape with 6 sides is a hexagon.
