How many gallons of water would it take to fill 3000 square feet?

Answer 1

1870.13 gallons per inch of depth.

144 sq. ins./sq. ft. X 3000 sq. ft.= 432,000 sq. ins.

1 gal. = 231 cu. ins. = 231 sq. ins X 1 in. deep.

432,000 sq. ins. / 231 sq. ins. per gal @ 1 in. depth = 1870.12987+ gallons @ 1 in.
