In a rectangular prism, the length, width and height may be of different lengths. A rectangular prism is also called a cuboid or rectangular solid. A cube is a special case of a cuboid in which all six faces are squares.
The volume of the above rectangular prism would be the product of the length, width and height that is
Volume of rectangular prism = lwh
Surface area of rectangular prism = 2(lw + wh + lh)
Worksheet to calculate the volume and surface area of a rectangular prism.
