What is the surface area of a rectangular prism with length 9, width 4, and height 6?

Explanation:
Surface area of a rectangular prism is the sum of the areas of all its faces. There are three distinct face sizes: length by width, length by height, and width by height, each appearing twice. So use 2(lw + lh + wh). For length 9, width 4, height 6: lw = 36, lh = 54, wh = 24. Add them: 36 + 54 + 24 = 114. Multiply by 2 to include the opposite faces: 228. Therefore, the surface area is 228.
