Regular prism

A regular prism is a prism whose bases are congruent regular polygons and whose lateral faces are rectangles (or parallelograms if the prism is oblique). In a right regular prism, the sides are rectangles and the axis is perpendicular to the bases.

Important properties

• The two bases are congruent regular polygons.

• All lateral faces are rectangles (in a right regular prism).

• The height is the perpendicular distance between the bases.

• The volume is given by $V = B \times h$, where $B$ is the area of the base and $h$ is the height.

• The surface area is $2B + P \times h$, where $P$ is the perimeter of the base.
