Multiple Choice A rectangular prism has a volume of 1,080 ft. The height of

Answer 1

The length of the prism is 15 feet.

Step-by-step explanation:

Step 1:

The volume of a rectangular prism is the product of its length, its width, and its height.

The volume of a rectangular prism = $(length)(width)(height).$

Assume the length of this prism is $l$ feet, the width of the prism is 9 feet and the height is 8 feet.

The volume of the prism is given as 1,080 cubic feet.

Step 2:

The volume of a rectangular prism = $(length)(width)(height).$

$1080=(l)(9)(8) = 72l,$

$l = \frac{1080}{72} = 15.$

So the length of the rectangular prism is 15 feet.
