This size tub holds 249 US gallons of water.
Making allowances for the flange and curvature, it is about 120 Imperial gallons.
Volume = (pi) R2 L = (pi) (30)2 (12) = 10,800 pi = 33,929.2 cubic inches = 146.88 gallons (rounded)
You didn't provide enough information to fully answer this question. Volume requires 3 dimensions, and you provided 2 (or didn't fully explain the 3rd). To determine volume, you need length, width and height LxWxH=Volume. I'll explain how to solve this math problem the best way I can. 1 gallon = 231 cubic inches http://www.onlineconversion.com/volume.htm Now that you know there are 231 cubic inches per gallon, determine the volume of water you need in inches. I'm going to guess you were meaning the tube is 12 inches long and either a 4 inch diameter. Volume of a cylinder can be acheived by multipling the area of the base times height. Assuming your cylinder is a perfect circle with an inside diameter of 4 inches, the base would be PI * r2 or 3.141592 * (2*2) or 12.535668 inches square. Multiply this times the height (12), and you'll get the cubic inches required to fill the cylinder...or 150.796416 cubic inches. Divide by 231 (cubic inches per gallon) equalling .6528 US gallons required to fill the tube.
Volume of a cylinder = (pi) R2 L = (pi) (10)2 (1,500 x 12) =5,654,866.8 cubic inches = 24,480 gallons (rounded)That's the volume of the section of pipe. We have no wayof knowing how much water is in it.
1 gallon = 231 cubic inches1 cubic foot = 1,728 cubic inches = 7.48052 gallons (rounded)2,722.5 cubic feet = 4,704,480 cubic inches = 20,365.7 gallons (rounded)whether there's anything in those cubic feet or not. Even if they're empty.

It will take 5,104.1 gallons of water to fill this cylinder.
If you fill it with 4 feet of water (48 inches), the pool will contain about 5,310 gallons of water.
To fill this pool to the very top you'll need about 1,480 gallons of water - less if you do not fill it all the way up.
Exactly 35.2332 gallons, but 36 to be safe.

Assuming the only thing in the aquarium is water, this tank could hold up to 19.8 gallons of water.
72 gallons is needed to fill the tank.
The volume is 23,430 cubic inches which would require 101.4 gallons to fill.
