You need to tell us how HIGH the tank is !
The area of rectangle is : 16.5
fill it until it is at 30 gallons...isn't it obvious
13,464.94 US gallons.
You don't tell us which measurement is the length. I shall assume that it's the 30 feet. This sort of calculation has to be done in two parts. Looking at the pool sideways, there is a rectangle 3 feet high and 30 feet long. That sits on top of a triangle which is 2 feet high at one end and tapers off, over a length of 30, to nothing. A) find the area of the rectangle - 30 x 3 = 90 square feet. B) find the area of the triangle - 1/2(30 x 2) = 30 square feet So, the side of the pool has an area of 120 square feet, and it is 23 feet wide. The volume is - 120 x 23 = 2,760 cubic feet. Here is were we get a problem. A 'gallon' can be an Imperial gallon - 0.16054365 cubic feet, or it can be a US gallon - 0.13368056 cubic feet. If the gallons are Imperial, then the pool will need 2,760 ÷ 0.16054365 = 17191.6 Gallons If the gallons are US, then the pool will need 2,760 ÷ 0.13368056 = 20646.2 Gallons (both those figures have been rounded to one decimal place.)
4745 gallons Best estimate I have.
Approx 4892 Imperial gallons.
There are 907.9202769 feet2 of water, but you will have to convert that into gallons.
It is 16.5 square feet.
29,610.94 gallons (rounded)
It depends but most are 11 feet high.
The base is 12feetsquared
