text: A polyhedron is called an $n$-gonal prism if two of its faces (the bases) are equal $n$-gons (not lying in the same plane), which can be obtained from each other by parallel translation, and the remaining faces are parallelograms, the opposite sides of which are the corresponding sides of the bases.
