Okay kiddo, a cord is a lot like a thick rope or string that can be used for lots of different things. When we talk about cord volume, it means how much space the cord takes up. Just like how you have toys that take up more space than others, some cords can take up more space than others. We measure cord volume in different units like meters or feet to help us understand how long or big a cord is. It's important to check cord volume when we use cords for things like tying or wrapping so that we know we have enough to do what we need to do.
