What is the volume of a cube with sides of length 3?

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

By substituting the side length into the formula, we perform the following calculation:

[

V = 3^3 = 3 \times 3 \times 3

]

First, we calculate ( 3 \times 3 ), which equals 9. Next, we multiply that result by 3:

[

9 \times 3 = 27

]

Thus, the volume of the cube is 27 cubic units. This matches the correct answer.

When evaluating the other possible answers, values like 18, 24, and 30 do not accurately reflect the volume calculated with the side length of 3 according to the formula for the volume of a cube. Therefore, the accurate volume derived from the given dimensions confirms that 27 is indeed the right choice.
