Denise is helping her dad build a rectangular prism. The height will be 8 ft. and the length will be 6 ft. If the volume of the clubhouse will be 288 ft. 3, what will be the width?

14 ft.
10 ft.
6 ft.
4 ft.

To find the width of the rectangular prism (clubhouse), we can use the formula for the volume of a rectangular prism:

\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]

We know the volume (288 ft³), the length (6 ft), and the height (8 ft). We can rearrange the formula to solve for width:

\[ \text{width} = \frac{\text{Volume}}{\text{length} \times \text{height}} \]

Now substitute the known values:

\[ \text{width} = \frac{288 \text{ ft}^3}{6 \text{ ft} \times 8 \text{ ft}} \]

Calculate the denominator:

\[ 6 \text{ ft} \times 8 \text{ ft} = 48 \text{ ft}^2 \]

Now divide the volume by this result:

\[ \text{width} = \frac{288 \text{ ft}^3}{48 \text{ ft}^2} = 6 \text{ ft} \]

Thus, the width of the clubhouse will be 6 ft.
