So I have two green coolers. One is pretty big but I don't know how big it is or how big the other one is. ( I looked on it everywhere and it isn't stated.)
So how do I go about figuring that out?
If I know how many cubic inches a gallon of water is I can start from there.
A gallon of water is 231 cubic inches. Just for the heck of it, what is the cube root of 231? It is 6.135 inches. Which means that if you had a cube with each side 6.135 inches it, and that were the internal dimensions and you filled it with water it would be ~exactly a gallon of water.
So the next step is to measure the internal dimensions of my cooler in terms of depth, width and length. Multiply those together and you have the cubic inch capacity. Divide your cubic inch capacity by 231 and you have gallons. Multiply that by 4 and you have the common product listing unit of coolers- in quarts!
But there is one problem. My coolers have a smaller length and width at the base than at the top. But the height is constant. So I will run the calculations two different ways. Max Vol at the top and Min Vol with the base dimensions. Then I will add the two and divide by two to get an average. And lastly if it is a fractional number I will know that they are not really listed for sale in fractions. So the one that is like mine for sale on an internet site with likely be an even number and perhaps it is a little higher number, seeing as that is how things usually are.
So I ran the math. One other thing that is important to know is how heavy the water only in that cooler would be if it were filled completely with water. Water weighs 8.34 pounds per gallon. Okay so I ran the numbers and placed them on my phone word file. And transferred that file here, for you to see.
Hopefully you see how this is done, what the constants are. And if you don't know how big your cooler is, take those three internal measurements of Depth, Width and Length and plug them in where they are in this on your own program or pad of paper and see.
Average quarts 37.6

Of course you could weigh it empty. Fill it completely with water. Weigh it then. And divide by 8.34 but you would be wasting water.
I would say that the big one is an 80 quart and the small one is a 40 quart.
How much would a 150 quart weigh filled with water (just the water)? 150/4*8.34= 312.75 pounds!
