To find the surface area of a rectangular prism, we need to calculate the area of each of its six faces and then add them together.
The formula to find the surface area of a rectangular prism is:
2lw + 2lh + 2wh
Given dimensions:
Length (l) = 7 inches
Width (w) = 3 inches
Height (h) = 11 inches
Plugging the values into the formula:
2(7)(3) + 2(7)(11) + 2(3)(11)
14 + 154 + 66
234
Therefore, the surface area of the rectangular prism is 234 square inches.
