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

1. 9 cm³

2. 18 cm³

3. 27 cm³

4. 36 cm³

The correct answer is: 27 cm³

To determine the volume of a cube, you can use the formula for volume, which is given by \( V = s^3 \), where \( s \) represents the length of a side of the cube. In this case, the side length is 3 cm. Plugging this value into the formula results in: \[ V = 3 \, \text{cm} \times 3 \, \text{cm} \times 3 \, \text{cm} = 27 \, \text{cm}^3 \] Therefore, the volume of the cube is 27 cubic centimeters. This value makes clear the spatial capacity of the cube, reflecting how much space it occupies. Understanding this calculation is crucial since it emphasizes the importance of using the right formula based on the geometric shape involved.
