To find the surface area of a rectangular prism, we need to calculate the area of each of the six faces and then add them together.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Given that the length (l) is 5 inches, the width (w) is 3 inches, and the height (h) is 4 inches, we can plug these values into the formula:
Surface Area = 2(5)(3) + 2(5)(4) + 2(3)(4)
Surface Area = 30 + 40 + 24
Surface Area = 94 in^2
Therefore, the surface area of the rectangular prism is 94 square inches.
