PrismIn general, a prism is a polyhedron having two congruent polygonal faces and all other faces being parallelograms. A right prism is a prism where the vertical polygons are not parallelograms but rectangles (the simplest right prism is shown at the left). Prisms that are not right prisms are known as oblique prisms. A special case of a right prism is the cuboid, where both the top and the bottom faces are rectangles. The volume of a right prism is given by the product of the base area A_{b} times the height h: V = A_{b}h. The surface of a prism is given by the product of the circumference of the base face times the height h plus twice the area of the base face.Regular Right Prisms Regular right prism have a regular polygon of n vertices as top and bottom faces. The relationship between the radius of the polygon r and its side a is determined by the following equation: The surface of a regular nprism can be calculated as follows: The volume of regular nprisms is given by
