Dear Sirs; I am wondering if you could tell me the equation to convert gallons to square foot. I have found that 1 cubic foot will hold 7.48 gallons of gasoline, but I would like to know how to come by this answer. I really appreciate your time.
Thank you,

Just interested

My dictionary tells me that there are 231 cubic inches in an American gallon. Thus

1 cubic inch is 1/231 = 0.004329 gallons.

A cubic foot is 12 inches by 12 inches by 12 inches and hence

1 cubic foot = 12 12 12 = 1728 cubic inches.

Hence

1 cubic foot = 1728 cubic inches = 1728 0.004329 = 7.48 gallons.
