Surface area of right rectangular prism practice
alculate the surface area of a right rectangular prism with dimensions w=12 in. , l=18 in. , and h=8 in. . How many square inches is the surface area?(1 point)
To calculate the surface area of a right rectangular prism, you need to find the sum of the areas of all of its faces.
The formula to calculate the surface area of a rectangular prism is given by:
Surface Area = 2lw + 2lh + 2wh
Substituting the given dimensions, we have:
Surface Area = 2(12 in)(18 in) + 2(12 in)(8 in) + 2(18 in)(8 in)
Simplifying this expression gives:
Surface Area = 432 in² + 192 in² + 288 in²
Adding the terms together, we get:
Surface Area = 912 in²
Therefore, the surface area of the right rectangular prism is 912 square inches.
