Question

The volume of this rectangular prism is 108 cubic feet.

Answer 1

Answer:

8 feet.

Step-by-step explanation:

We have been given that the volume of this rectangular prism is 108 cubic feet. Width are height are 4.5 feet and 3 feet. We are asked to find the length of the prism.

We know that volume of rectangular prism is product of length, height and width of prism.

$V=lwh$

Upon substituting our given values in volume formula, we will get:  

$108\text{ ft}^3=l(4.5\text{ ft})(3\text{ ft})$

$108\text{ ft}^3=l(13.5\text{ ft}^2)$

$l(13.5\text{ ft}^2)=108\text{ ft}^3$

$\frac{l(13.5\text{ ft}^2)}{13.5\text{ ft}^2}=\frac{108\text{ ft}^3}{13.5\text{ ft}^2}$

$l=8\text{ ft}$

Therefore, the length d the prism is 8 feet.

Answer 2

Answer:

8 feet

Step-by-step explanation:

4.5 times 3 is 13.5 and 108 divided by 13.5 is 8
