Calculate the volume of a cube with a side length of 3 cm.

To find the volume of a cube, the formula used is ( V = s^3 ), where ( s ) represents the length of one side of the cube. In this case, the side length of the cube is given as 3 cm.

Using the formula:

[

V = 3^3

]

[

V = 3 \times 3 \times 3

]

[

V = 27 , \text{cm}³

]

Thus, the volume of the cube is indeed 27 cm³. This calculation confirms that the correct answer is 27 cm³, which corresponds to the choice provided.

The other options do not correctly reflect the volume that results from a side length of 3 cm when using the cube volume formula, as they either involve incorrect arithmetic or incorrect application of the formula.
