The surface area of a rectangular prism can be calculated using the formula: 2lw + 2lh + 2wh, where l = length, w = width, and h = height.
Plugging in the values:
2(3)(9) + 2(3)(4) + 2(9)(4)
= 54 + 24 + 72
= 150 in2
Therefore, the surface area of the rectangular prism is 150 in2.
The surface area of a rectangular prism that has height of 4 inches, width of 9 inches and length of 3 inches = ____________ in2.
