2. Example 1

3. Pattern? In other words, Area of 1st x k2 = Area of 2nd
When all lengths are multiplied by a scale factor k, the Areas are multiplied by k2
In other words,
Area of 1st x k2 = Area of 2nd

4. Example 2
The volume of the cuboid 3cm x 4cm x 5cm = 60 cm3

5. Pattern? Volume of 1st x K3 = Volume of 2nd
When all the lengths are multiplied by K,
The volumes are multiplied by K3
Volume of 1st x K3 = Volume of 2nd

6. Let’s do some practice….
