Bot GPT 3.5 To find the surface area of a rectangular prism, we need to calculate the area of each individual face and then add them all together.
Surface area = 2lw + 2lh + 2wh
Given:
Length (l) = 3 in
Width (w) = 9 in
Height (h) = 10 in
Surface area = 2(3)(9) + 2(3)(10) + 2(9)(10)
Surface area = 54 + 60 + 180
Surface area = 294
Therefore, the surface area of the rectangular prism is 294 square inches.
