How many cubic inches are in one cubic foot of water?

One cubic foot is defined as the volume of a cube that measures one foot on each side. Since there are 12 inches in one foot, the volume in cubic inches can be calculated by raising the number of inches to the third power.

The calculation involves taking 12 (the length in inches of one side of the cube) and cubing it, which means multiplying 12 by itself three times:

12 inches × 12 inches × 12 inches = 1728 cubic inches.

Therefore, one cubic foot of water is equivalent to 1728 cubic inches, confirming that the correct answer is indeed 1728 cubic inches. This understanding is essential because it illustrates the conversion between different units of measurement used in various calculations not only in fire apparatus engineering but in other engineering and construction contexts as well.
