What is the surface area of a rectangular prism with length 8, width 3, and height 5?

Explanation:
Finding the surface area of a rectangular prism means adding up the areas of all six faces. The formula is 2(lw + lh + wh). With length 8, width 3, and height 5, compute lw = 24, lh = 40, and wh = 15. Add them: 24 + 40 + 15 = 79. Double that for the two of each face: 2 × 79 = 158. So the surface area is 158 square units.
