Question

I need help with this​

Answer 1

The correct answer is B: 3 cubic feet.

Explanation:

If you want to find the volume of a rectangular prism, you need to know the length, width, and height. The first rectangular prism is a cube with a length of 3 feet, so the volume of the figure would be
`3^(3)=27 ft^(3)`. The second rectangular prism has a length of 3 feet, a width of 2 feet, and a height of 4 feet, so the volume of the prism would be 3 × 2 × 4 =
`24 ft^(3)`. Now that you know the 2 volumes, you need to subtract the volumes in order to find the difference, which is 27 - 24 = 3
`ft^(3)`.
