Finding Area and Volume of a Prism
The volume of a prism is the area of the base face multiplied by the height. (If the prism is not a right prism, then the height is merely the perpendicular height from the base face.) The surface area of a prism is calculated by the sum of perimeter of the base face multiplied by the height of the prism and twice the area of a base face.
