When you own an outdoor swimming pool, in the spring you need to "shock" it, which means add a large amount of chlorine, in order to kill all the backteria and algea that accumulated over the fall/winter/spring. But chlorine is expensive, so you don't want to add too much (and waste it). In order to figure out how much to add, you need to figure out the volume of your pool, since the label on the chlorine tells you how much to add per litre of water.
You need to know how big to make the quilt. For example, a crib quilt might be in the neighborhood of 50 x 60 inches, whereas a queen size quilt would be more like 94 x 108 inches. You can figure this out by measuring the mattress and allowing for the length of overhang you want (on both sides, and the bottom, and enough to cover the pillows if desired on the top). Or, you can find a chart that tells you standard quilt sizes.
