In this video, I'm going to teach you how to figure cubic feet. So, first, to work out cubic feet, you first need to know how to work out square foot. So, I'm going to draw a rectangle. Now, this rectangle has two dimensions, the width and the height. So, this is the width, and this is the height. Now, all you need to do is take the measurement of the width, take the measurement of the height, and multiply the two together. So, I'm going to measure this width. That width is two feet. And this height, that is one foot. So, all we need to do is take the width, take the height, and multiply them together. Two times one equals two, and that is two square foot. So, the square footage of this square is two, and that's how to figure out square foot. Okay, to figure out cubic feet, we now have three dimensions. It's much the same as square foot but with three numbers and all you do is multiply three together. So, let's look at a cube. That's a cube. That has three dimensions. Firstly, the width. This is the height, and this back here, this is the depth. Now, if I measure this cube, this width, that's two feet, this height, two feet, and the depth is one foot. To figure out the cubic feet, multiply two (the width) by the height (two), by the depth (one). Two times two is four, times one is four, and this is four cubic feet. And that's how to figure cubic feet. .
