The question makes no sense.
Presumably it refers to diesel rather than deseil!
A square foot is a measure of area in 2-dimensional space whereas both diesel and water are measured in 3-dimesional space. A typical measure was a gallon - now antiquated. However, a gallon of water is exactly the same as a gallon of diesel or a gallon of any other fluid, for that matter!
There are no gallons of water in a square foot. Gallons is a unit of volume, and square feet is a unit of area, not volume. If you are asking about cubic feet, however, the answer is there are about 7.5 gallons in a cubic foot.
770/500 = 1.54 gallons per square foot
7,480.52 gallons for every inch of depth
A square foot cannot hold water its 2 dimensional. What you see is what you get . A one cubic foot container can hold 7.48 US gallons of liquid.
== 478.79 gallons, there are 7.481 gallons in a square foot. So that is 64 x 7.481== 478.79.==http://dictionary.reference.com/writing/styleguide/weights.html
A square foot has no volume. if you are asking how many gallons are in a cubic foot the answer id 7.4805195.
About 1,246 Imperial gallons (UK) or about 1,500 US gallons.
A gallon is a measure of volume whereas a square foot is a measure of area. So there are no gallons in a square foot and no square feet in a gallon.
One cubic foot of water is 7.4805 gallons.
1 gallon
A square foot equals an area 12"Wide x 12"Long x 1"Deep. A cubic foot equals an area 12"W x 12"L x 12"D. Therefore, a cubic foot contains 12 square feet. A cubic foot contains 7.48 gallons of water (trust me). You divide a cubic foot by 12 to get 12 square feet, therefore you would divide 7.48 by 12 to get the amount of water contained in 1 square foot. 7.48 divided by 12 equals .623 gallons. For every inch of rainfall there will be .623 gallons of water falling on every square foot.
To discover the number of gallons of water in an 850 square foot pool, we'll need to know the depth of the pool. For a pool with 850 square feet and a known depth in feet, we'll find the volume by multiplying 850 ft2 by the depth in feet. With the answer in hand (and it will be in ft3 because we'll have a volume of water), we can find the number of gallons. There are about 7.48 gallons of water in a cubic foot. By multiplying our volume in ft3 by 7.48 (which is the conversion factor), we'll have discovered the volume of the pool in gallons.
