What is the surface area of the rectangular prism?
An image of a rectangular prism, a length of 10 in, a width of 9 in, and a height of 3 in.
The formula for finding the surface area of a rectangular prism is: 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Plugging in the values given:
Surface area = 2(10)(9) + 2(10)(3) + 2(9)(3)
Surface area = 180 + 60 + 54
Surface area = 294 in^2
Therefore, the surface area of the rectangular prism is 294 square inches.
