What is the volume of a cube with each side measuring 3 feet?

To find the volume of a cube, you use the formula V = s³, where V represents volume and s represents the length of one side of the cube. In this case, each side of the cube measures 3 feet.

Calculating the volume involves raising the side length to the third power:

V = 3 feet × 3 feet × 3 feet = 27 cubic feet.

Hence, the volume of the cube is 27 cubic feet, confirming the correctness of the answer. Understanding this formula is crucial in HVAC applications where volume calculations are often necessary for determining air flow and system capacities.
