1. Finding VOLUME

2. The OBJECTS

3. The OBJECTS
Let's try this one

4. FORMULA?
L x W x H
Length = 6cm

5. FORMULA?
L x W x H
Length = 6cm
Height = 4cm

6. FORMULA?
L x W x H
Length = 6cm
Width = 2cm
Height = 4cm

7. FORMULA? SO MULTIPLY 'EM! L x W x H Length = 6cm Width = 2cm
Height = 4cm
SO MULTIPLY 'EM!

8. 6 x 2 x 4 = 3
48cm
x 4 =
=12

9. So, the VOLUME of this object is 48 cm3
Nice work.

10. The OBJECTS
Let's try this one

11. Find VOLUME
Can't do L x W x H
it's an irregular shape.
hmmmm...

12. The METHOD
-40mL
-35mL
-30mL
-25mL
-20mL
-15mL
-10mL
-5mL

13. 1. Note the water level 20 mL -40mL -35mL -30mL -25mL -20mL -15mL

14. 2. Place the object in liquid
-40mL
-35mL
-30mL
-25mL
-20mL
-15mL
-10mL
-5mL

15. -40mL
-35mL
-30mL
-25mL
-20mL
-15mL
-10mL
-5mL

16. 3. Note difference in water level
35 mL
-40mL
-35mL
-30mL
-25mL
-20mL
-15mL
-10mL
-5mL
20 mL

17. The water level changed 15mL
We can say the rock displaced 15mL

18. It gets better! 3 1mL = 1cm so... 3 15mL = 15cm -40mL -35mL -30mL

19. Volume of our rock… 3
= 15cm
Great work!
