To calculate the surface area of a right rectangular prism, you need to find the area of each face and add them together.
The formula to find the surface area of a right rectangular prism is:
Surface Area = 2(length * width + width * height + length * height)
Given the dimensions:
Length = 12 inches
Width = 18 inches
Height = 8 inches
Surface Area = 2(12 * 18 + 18 * 8 + 12 * 8)
Surface Area = 2(216 + 144 + 96)
Surface Area = 2(456)
Surface Area = 912 square inches
Therefore, the surface area of the right rectangular prism is 912 square inches.
Calculate the surface area at the right rectangular prism with dimensions with equals 12 inches length equals 18 inches in height equals 8 inches. How many square inches is the surface area one point.
