The surface area of the rectangular prism can be found by adding up the areas of all six faces.
To find the surface area, use the formula:
Surface Area = 2lw + 2lh + 2wh
Given:
Length (l) = 5ft
Width (w) = 2ft
Height (h) = 8ft
Substitute the values into the formula:
Surface Area = 2(5)(2) + 2(5)(8) + 2(2)(8)
Surface Area = 20 + 80 + 32
Surface Area = 132
Therefore, the surface area of the rectangular prism is 132 square feet.
