Calculate the surface area of a right rectangular prism with dimensions, w=12in., l=18in., and h=8in. How many square inches is the surface area?
The surface area of a right rectangular prism is calculated by adding the areas of all of its faces.
The formula to calculate the surface area of a right rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Given that the dimensions of the prism are w = 12in., l = 18in., and h = 8in., we can substitute these values into the formula:
Surface Area = 2(12in.)(18in.) + 2(12in.)(8in.) + 2(18in.)(8in.)
Surface Area = 432in² + 192in² + 288in²
Surface Area = 912in²
Therefore, the surface area of the right rectangular prism is 912 square inches.
