Don't be a blockhead when it comes to cubes! You see them in iced tea, you play with them, you might even be living in one! It's easy to calculate cubic units, so turn up the volume on learning cubes!

Quick Query

How many blocks will fit in your toy box if each block is one cubic unit? Do you need to know that? Sure!

What do boxes, blocks, and dice have in common?

They are all *cubes*! A cube is a three-dimensional shape.

*Volume* measures the amount of space an object occupies. To find the volume of a cube, we need to know three measurements. We need to know the *length*, *width*, and *height* of the cube.

We can use this formula to find the volume: Volume = Length x Width x Height

The volume of a unit cube is 1 cubic unit.

Look at the example below. This solid is made of 4 unit cubes:

Its volume is 4 cubic units.

If each side of the cube measures 1 centimeter (cm), then the unit cube can be measured in cubic centimeters (cm^{3}).

Imagine the example above is made of 1-cm cubes. What is the volume of this solid?

Two 1-cm cubes will have a volume of 2 cubic centimeters, or 2 cm^{3}.

Imagine you have a toy box and you want to know how many blocks you can fit in the box. By using cubic units, you can measure the volume of the box.

- Can you think of other times that you may need to find the volume of solids in real life? Share your ideas with your parent or teacher.
