Yet, a prism can be any stack of shapes. if you have to determine the area or volume of an odd prism, you can rely on the area (a) and the perimeter (p) of the base shape. many times, this formula will use the height of the prism, or depth (d), rather than the length (l), though you may see either abbreviation. surface area = 2a pd; volume = ad.
