What is the volume of a cube that has a side length of 3?

The volume of a cube is calculated using the formula ( V = s^3 ), where ( s ) is the length of one side of the cube. In this case, the side length is 3.

To find the volume, you would raise the side length to the power of 3:

[ V = 3^3 = 3 \times 3 \times 3 = 27. ]

Thus, when a cube has a side length of 3, its volume is indeed 27 cubic units. This demonstrates the application of exponentiation in calculating volume, which is integral in geometry when dealing with three-dimensional shapes.
