How many gallons are in 1 ft^3?

To determine how many gallons are in one cubic foot, it's important to recognize the conversion between these two units of volume measurement. One cubic foot is defined as a cube with each side measuring one foot, which is equivalent to 12 inches per side.

When converting cubic feet to gallons, we use the fact that there are 7.48 gallons in one cubic foot. This conversion factor is derived from the standard definitions of gallons and cubic feet, particularly in the context of U.S. measurement systems.

The value of 7.48 comes from the equivalences that 1 gallon is approximately equal to 0.133681 cubic feet, and thus by calculating the reciprocal, we find how many gallons fit into a cubic foot. Therefore, when asked how many gallons are in 1 ft³, the correct answer is 7.48.

This understanding is critical for various applications, particularly in fields involving fluid dynamics, water treatment, and any situation where accurate volume measurements are necessary.
