The surface area of a rectangular prism can be found using the formula:
Surface Area = 2lw + 2lh + 2wh
In this case,
l = 9 inches
w = 3 inches
h = 10 inches
Plugging in these values,
Surface Area = 2(9)(3) + 2(9)(10) + 2(3)(10)
Surface Area = 54 + 180 + 60
Surface Area = 294 square inches
Therefore, the surface area of the rectangular prism is 294 square inches.
