Cubic foot

A cubic foot is a way to measure how much space something takes up. It's like a big box that is one foot long, one foot wide, and one foot tall.

Imagine if you had three blocks that were each one foot long, one foot wide, and one foot tall. If you were to stack them on top of each other, they would take up three cubic feet of space.

Now imagine if you had a big container that was also one foot long, one foot wide, and one foot tall. If you filled that container up with water, it would take up one cubic foot of space.

In summary, a cubic foot is a measurement that tells you how big something is by measuring the length, width, and height of it and then multiplying those numbers together.
