Okay....

12 inches in a foot

5280 feet in a mile.

I have an area of 25 miles that has raised 5 inches with liquid.

What is the volume of the liquid (the increased amount)?

My brain is on off at the moment. Either someone turn my head on or help me with the answer.

I don't even know if I am asking this right. I want to know the cubic ft volume. I could have been a scientist if I didn't suck so bad at word problems.

I have to estimate

__water volume__ somewhat frequently when filling or drawing down our wetlands and dawg training ponds. So I needed to learn a few basic facts. One acre-foot is the volume of water sufficient to cover an acre of land to a depth of 1 foot, = 43560 cubic feet, approximately 325851 U.S. gallons.

In your problem above, you stated that the area is 25 miles and 5" in depth. I'm assuming that's precisely 25 square miles. If so, that means you have an area that is 696,960,000 sq ft (I used 5 miles squared = 25 miles X 43,560 to compute total square feet).

696,960,000 is also the number of cubic feet (1 ft sqare by 1 ft deep) in 25 square miles. Divide that by 43,560 (sq ft in an acre) and you get 16,000 acres.

16,000 acres X 325,851 (gals per acre foot of water) equals 5,213,616,000 gallons of water in a 25 square mile area that is exactly 1 foot deep.

Divide that by 12 to get gallons per inch and multiply back by 5 and you will find that there are 2,172,340,000 gallons of water in that 25 square mile area five inches deep.
