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
There are 7.48052 US gallons per cubic foot.
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.
