The problem asks to find the volume of a cube. The length of each side of the cube is given as 9 ft.

1. Problem Description

The problem asks to find the volume of a cube. The length of each side of the cube is given as 9 ft.

2. Solution Steps

The volume of a cube is given by the formula:

$V = s^3$

where $V$ is the volume and $s$ is the side length of the cube.

In this problem, $s = 9$ ft. Therefore, the volume is:

$V = (9 \text{ ft})^3 = 9 \text{ ft} \times 9 \text{ ft} \times 9 \text{ ft} = 81 \text{ ft}^2 \times 9 \text{ ft} = 729 \text{ ft}^3$

3. Final Answer

The volume is 729 cubic feet.
