How do you find volume in gallons of a rectangular tank?

Answer 1

Okay, this is a pretty easy formula, especially because you are working with liquid, and volume is the unit of measurement used mainly in science and math, as well as other areas and fields of study, to measure different types of liquids. So let's get started.

First let's start by measuring top to bottom (height), side to side (width), then measure front to back (depth), ( some people consider top to bottom the depth, when measuring in volumes, side to side as the length and front to back as width. So its however you prefer, as long as the measurements are accurate). Now multiply the height x width x depth = volume per cubic inches. To convert volume into gallons first you have to understand that 1 gallon is equal to 231 cubic inches. If you can remember that, you will never have a problem converting volume per cubic inch into gallons, again. Now take the volume and divide it by 231 c/i. This will give you the amount of gallons out of the total amount of volume per cubic inches.

IE.

height = 10"

width = 20"

depth = 12"

So, 10" x 20" x 12" = 2400 c/i

Next, divide 2400 by 231 for the answer in gallons.

2400/231=10.38 gal.

So a rectangular tank with these dimensions of volume per cubic inch would have a capacity of 10.38 gallons.

(These measurements were taken of my fish tank, so this is a factual equation)

I hope this is easy and simple enough for everyone to comprehend.

And remember the only stupid question is the question not asked.

I may have answered the question backwards and if i did i apologize. To get volume from gallons first understand that the unit of measurements used to measure liquids are measured in volumes. So from the previous answer we learned that 1 gallon is equal to a volume of 231 cubic inches. Now I don't know the conversion you're looking for to get volume from gallons, so I'll give you the volume in cubic inches. Hit me up if you need it in another converted measurement and I'll get back to you. But for now; If 1 gallon equals 231 cubic inches, and there is 4 quarts in a gallon, than the total cubic inches in a quart would be about 57.75. The equation would be the cubic inches in a gallon divided by 4 quarts = 57.75 cubic inches in a quart. Cubic inches in a pint would be this equation. There's 2 pints in a quart, so you the cubic inches in your quart (57.75) and divide it by the amount of pints in a quart (2) which would give you a total of 28.875 cubic inches.

I.e.

First divide the cubic inches in a gallon by the amount of quarts in a gallon:

231c.in./4qt.= 57.75 c/i

Now divide the cubic inches in 1 quart by the amount of pints in a quart which is 2:

57.75 / 2pt. = 28.875 c/i

So there is 28.875 c/i in a pint.

Hope this helps...
