What is Volume?

Definition Volume

The volume of an object is the amount of space it takes up. We measure volume by counting how many cubic units can fit inside it. A cubic unit is a cube with sides that are 1 unit long.

Method Counting Cubes to Find Volume

To find the volume of a shape made of blocks, simply count the total number of blocks (cubic units) it is made from. A good strategy is to count the blocks in each layer.

Example

Find the volume of the shape below.

Answer
