Question

What is the surface area of a rectangular prism that has a length of 30 centimeters, a height of 20 centimeters, and a width of 6 centimeters?

Answer 1

1800

Answer 2

Surface Area = 2(30)(6) + 2(30)(20) + 2(6)(20)
Surface Area = 360 + 1200 + 240
Surface Area = 1560 + 240
Surface Area = 1800 cm^2

Therefore, the surface area of the rectangular prism is 1800 square centimeters.
