To find the surface area of a rectangular prism, you need to calculate the sum of the areas of all six faces.
In general, the formula to calculate the surface area of a rectangular prism is:
Surface area = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height of the rectangular prism.
For example, if the length of the rectangular prism is 5 inches, the width is 3 inches, and the height is 4 inches, then the surface area would be:
Surface area = 2(5)(3) + 2(5)(4) + 2(3)(4)
Surface area = 30 + 40 + 24
Surface area = 94 square inches
So, the surface area of the rectangular prism in this example would be 94 square inches.
