Question

A storage container is in the shape of a rectangular prism. The contamer has a length of 5 feet, a width of 9 fect, and a height of 8 feet. What is the surface area of the container.

a. 360ft²
b. 314ft³
c. 157ft²
d. 22ft²

Answer 1

The surface area of the container is 314 ft².

Step-by-step explanation:

To calculate the surface area of the container, we need to find the area of each face and then add them together. A rectangular prism has 6 faces. The formula for the surface area of a rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

Using the given dimensions of the container, we can plug in the values:

Surface Area = 2(5)(9) + 2(5)(8) + 2(9)(8) = 90 + 80 + 144 = 314 ft²
