To calculate the surface area of a right rectangular prism, you need to find the area of each face and then add them together.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Given:
w = 12 in. (width)
l = 18 in. (length)
h = 8 in. (height)
Substituting these values into the formula:
Surface Area = 2(12)(18) + 2(12)(8) + 2(18)(8)
Surface Area = 432 + 192 + 288
Surface Area = 912 square inches
Therefore, the surface area of the right rectangular prism is 912 square inches.
