Question

Number of surfaces of a regular prism of n sides is

Answer 1

Step-by-step explanation:

In geometry, a prism is a polyhedron comprising an n-sided polygonal base, a second base which is a translated copy (rigidly moved without rotation) of the first, and n other faces (necessarily all parallelograms) joining corresponding sides of the two bases. All cross-sections parallel to the bases are translations of the bases. Prisms are named for their bases; example: a prism with a pentagonal base is called a pentagonal prism. The prisms are a subclass of the prismatoids.
