Answer 2

Answer: A.
`180\ ft^3`

Explanation:

Given: A driveway that is 30 feet long, 18 feet wide, and 4 inches thick.

We know that 1 foot = 12 inches

Therefore, 4 inches =
`(4)/(12)=(1)/(3)\ feet`

We know that the volume of a rectangular prism is given by :-

`\text{Volume}=length* width* height`

Now, the volume of rectangular prism is given by :-

`\text{Volume}=30*18*(1)/(3)=180\ ft^3`
