To find the surface area of a rectangular prism, you need to calculate the area of all six faces and then add them up.
The formula for the surface area of a rectangular prism is:
2lw + 2lh + 2wh
Given dimensions: l = 7 in, w = 3 in, h = 11 in
Substitute the values into the formula:
Surface area = 2(7)(3) + 2(7)(11) + 2(3)(11)
Surface area = 42 + 154 + 66
Surface area = 262 in^2
Therefore, the surface area of the rectangular prism is 262 in^2.
The correct answer is:
262 in.2
262 in squared
