A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
It is a triangular prism.
The faces do not have specific names.
It could be called a square prism but a more common name would be a cuboid.
Nonagon
Divide the number of vertices by 3. Find the name of the polygon with that many sides. The prism has that polygon as a base. For example, a prism with 24 vertices. Divide by 3 so that is 8. An 8 sided polygon is an octagon. The name is an octagon-based prism.
A prism is often named according to its base: one of the pair of congruent and parallel polygonal faces. In that case, if the base is a polygon with n sides, then the prism has 2*n vertices.
It is a triangular prism.
The faces do not have specific names.
