To find the volume of a cube, you can use the formula for volume, which is the length of one side cubed (s³). In this case, the side length of the cube is 3 cm.

Calculating the volume involves raising the side length to the third power:

3 cm × 3 cm × 3 cm = 3³ = 27 cm³.

Thus, the volume of the cube with a side length of 3 cm is 27 cm³. This confirms that the correct answer is indeed 27 cm³.

The other options do not represent the correct volume calculated from the given side length. 9 cm³ would be the result of squaring the side length (3 cm × 3 cm), while 18 cm³ or 36 cm³ do not correspond to any operation correctly applied to the side length.
