The surface area of a rectangular prism with length l, width w, and height h can be calculated using the formula below.
S=2(l w+l h+wh)
The terms inside the parentheses represent the area of the three possible different sized faces. Each term is multiplied by 2, because opposite faces on a rectangular prism have equal dimensions. We are given that l = 8, w = 6, and h = 4. Let's substitute these values into the formula to calculate S.
