# 8.08 Find volumes using unit cubes

Lesson

## Are you ready?

We have counted squares to  find the area of a shape  and can use that to help us find the volume in this lesson. Let's try this problem to review.

### Examples

#### Example 1

Find the area of the shape below.

Worked Solution
Create a strategy

Count the total number of squares.

Apply the idea

There are 5 square inside the shape.

\text{ Area }= 5\, \text{units}^2

Idea summary

To find the amount of space a shape takes up, we can use a unit square.

## Volume with unit cubes

Let's see how we use unit cubes to find the volume of shapes.

### Examples

#### Example 2

In this figure, 1\text{ block}=1\text{ cm}^3. What is the volume of the solid figure?

Worked Solution
Create a strategy

Count the total number of blocks.

Apply the idea

There are 10 blocks in the solid.

\text{Volume}=10\text{ cm}^3

Idea summary

Volume means the amount of space a 3D shape takes up.

### Outcomes
