231 cubic inches equal one gallon, and 7.4805 gallons equal one cubic foot.
For the contents of a greater diameter than any in the table, take the quantity opposite one-_half_ said diameter and multiply it by 4. Thus, the number of cubic feet in one foot length of a pipe 80 inches in diameter, is equal to 8.728 × 4 = 34.912 cubic feet. So also with gallons and areas.
