In this lesson, you will learn about the concept of volume in math. We will discuss what volume is, how to calculate volume, and the units of volume. The units of volume are cubic units such as cubic cm, cubic meters, cubic km, cubic feet, etc. In order to understand volume, we must visualize the shape containing a number of cubes inside. The number of cubes that we can fit in the shape is called the volume in cubic centimeters, for example. A cubic centimeter is a cube where all sides are 1 cm long. In order to calculate the volume, we multiply the length by the width by the height. In this way we find how many cubes will fit inside of the shape, which is its volume.
