The volume of a cube is the amount of space it occupies. To calculate the volume, you use the formula V = s^3 , where V represents volume and s is the length of one side of the cube. Since all sides of a cube are equal, you simply multiply the length of one side by itself three times. For example, if a cube has a side length of 2 units, its volume would be 2 \times 2 \times 2 = 8 cubic units. This measurement is important in various fields, including mathematics, architecture, and engineering, where understanding space and capacity is essential.
