How many gallons are there in 1 cubic foot of water?

• A. 5.0 gallons
• B. 7.5 gallons
• C. 8.0 gallons
• D. 10.0 gallons

Answer: (B)

One cubic foot of water contains 7.5 gallons. This is based on the conversion factor that defines the volume relationship between cubic feet and gallons in the United States customary system. To visualize this, consider that a cubic foot is a solid cube with each side measuring one foot. Since one gallon is equivalent to 231 cubic inches, and there are 1,728 cubic inches in a cubic foot (12 inches x 12 inches x 12 inches), dividing 1,728 cubic inches by 231 cubic inches gives you approximately 7.48 gallons. For practical purposes, this is often rounded to 7.5 gallons. This conversion is important in irrigation and water management as it helps in measuring water supply and usage effectively.
