What is the surface area of the rectangular prism
10 in bottom 9 in wide 3 in tall
The formula to calculate 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.
Given:
l = 10 in
w = 9 in
h = 3 in
Plugging the values into the formula:
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.
