The surface area of a rectangular prism is calculated by finding the area of each face and adding them together.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Plugging in the values:
Surface Area = 2(10*9) + 2(10*3) + 2(9*3)
Surface Area = 2(90) + 2(30) + 2(27)
Surface Area = 180 + 60 + 54
Surface Area = 294
Therefore, the surface area of the rectangular prism is 294 square inches.
