Surface Area of Prisms
Surface area is a two-dimensional property of a three-dimensional figure. Prisms have two congruent, parallel bases separated by lateral faces. Lateral faces are congruent rectangles with a height equal to the prism, unless oblique, and bases equal to the side lengths of the congruent bases. Therefore, to find the surface area of prisms, find the area of the bases and the lateral faces and sum them.
