What is the surface area of the rectangular prism? (1 point) lengths are 8 cm, 9 cm and 5 cm.
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 that the lengths are 8 cm, 9 cm, and 5 cm, we can plug those values into the formula:
Surface Area = 2(8)(9) + 2(8)(5) + 2(9)(5)
Surface Area = 144 + 80 + 90
Surface Area = 314 cm^2
Therefore, the surface area of the rectangular prism is 314 cm^2.
