An octagonal prism has 10 faces. The octagonal prism can be seen to have ended shaped like octagons. That's an 8-sided figure. is a 3-dimensional form, and if it has octagons on each end, it is going to have 8 faces. That's a face for each side of the octagon. The 8 faces of the body of the prism are added to the two faces (one on each end) for a total of 10 faces. (The illustration is a pentagonal prism.). An n-gonal prism has n+2 faces.
The prism has two bases, all one needs to know is how many other faces it has. That is determined by the number of sides on the base. A hexagonal prism will have the two hexagonal bases, and six more faces, one for each side of the hexagonal base, for a total of eight faces. Children are often quite pleased when they discover, on their own, that they can figure out the number of faces without counting.
