Question

The surface area of a rectangular prism is found using the formula SA = 2(lw + lh + wh), where l is length, w is width, and h is height. What is the surface area (in square meters) of a rectangular prism with length 5 m, width 12 m, and height 6 m?

Answer 1

Since we have the numbers, we just have to plug them into the equation. 

SA = 2 × (5 × 12) + (5 × 6) + (12 × 6)

SA = 2(60 + 30 + 72)

SA = 324 m²
