What is the volume of a cube with a side length of 3 units?

To find the volume of a cube, you use the formula V = s³, where V represents the volume and s represents the side length of the cube. In this case, the side length is given as 3 units.

Calculating the volume, you would do the following:

V = 3³

V = 3 × 3 × 3

V = 27 cubic units

Therefore, the volume of the cube with a side length of 3 units is 27 cubic units. This corresponds to the correct answer.

The calculation confirms that for any cube, the volume increases rapidly as the side length increases, since it is cubic growth. In this instance, each dimension contributes equally to the overall volume, leading to a final result of 27 cubic units.
