How is the volume of a cube calculated?

The volume of a cube is determined using the formula where you take the length of one side and raise it to the third power, effectively cubing it. Since all sides of a cube are equal in length, if you denote the length of a side as "s," the volume can be expressed mathematically as ( V = s^3 ).

This makes option B the correct answer because it succinctly represents the calculation for the volume of a cube by cubing the length of one of its edges. In contrast, the other options describe volume calculations for different shapes or are not applicable to a cube specifically. For example, multiplying length, width, and height applies to rectangular prisms, not cubes where all dimensions are equal. Similarly, calculating volume as base times height is typically used for prisms with different base shapes.
