6 sides.................BUT:_ i beg to differ with 'Contributor"
a hexagon is a polygon with six edges and six vertices. A regular hexagon has Schläfli symbol {6}. The total of the internal angles of any hexagon is 720°.
So a hexagon rod or bar (Rifle barrel/) has Six Flatsaround the circumference and a FLAT (or other shape) at each end, making EIGHT.
A hexagon cut from paper ... has TWO FLAT surfaces, but it has Six straight edges.

There are 2 flat surfaces, both are circles.
It has 6 faces which are its flat surfaces.
5 Flat surfaces 4 flat surfaces (3 for the sides and 1 for the base).
A cuboid has got six flat surfaces.
