Calculate 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) in.2
To calculate the surface area of a right rectangular prism, we need to find the area of each face and then add them together.
The formula to find the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Substituting the given values:
Surface Area = 2(12)(18) + 2(12)(8) + 2(18)(8)
Surface Area = 432 + 192 + 288
Surface Area = 912
The surface area of the right rectangular prism is 912 square inches.
