To find the surface area of a 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:
Length (l) = 12 in
Width (w) = 5 in
Height (h) = 3 in
Substitute these values into the formula:
Surface Area = 2(12)(5) + 2(12)(3) + 2(5)(3)
Surface Area = 120 + 72 + 30
Surface Area = 222 in^2
Therefore, the surface area of the rectangular prism is 222 square inches.
Solve for the surface area of the rectangular prism. (1 point)
the illustration shows a rectangular prism with the length of 12 in a weight of 5 in and a height of 3 in
