square inches

Answer 1

To find the surface area of a rectangular prism, you can use the formula:

Surface Area = 2lw + 2lh + 2wh

Given:
Length (l) = 10 inches
Width (w) = 9 inches
Height (h) = 3 inches

Surface Area = 2(10)(9) + 2(10)(3) + 2(9)(3)
Surface Area = 180 + 60 + 54
Surface Area = 294 square inches

Therefore, the surface area of the rectangular prism is 294 square inches.
