what is the approximate surface area of the prism?
The surface area of a figure is the sum of the area of all surfaces of a figure. Surface Area is often abbreviated S.A. The surface area of a prism or cylinder is the lateral area plus the area of each base. Since the bases for a prism or cylinder are congruent, this is often expressed as twice the area of the base. The surface area of a pyramid or cone is the lateral area plus the area of the single base.
