1 Finding VOLUME

2 What is VOLUME? The amount of space that a 3-dimensional object takes up. Anything that exists, has volume…

3 The OBJECTS

4

5 FORMULA? Length = 6cm Volume = L x W x H

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

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

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

9 6 cm x 2 cm x 4 cm = 48 cm 3 Volume = L x W x H =

10 So, the VOLUME (the amount of space that this 3 dimensional object takes up) of this object is 48 cm 3

11 The OBJECTS

12 Find VOLUME

13 The METHOD – Finding Volume by Water Displacement -40mL -35mL -30mL -25mL -20mL -15mL -10mL -5mL

14 1. Note the water level -40mL -35mL -30mL -25mL -20mL -15mL -10mL -5mL

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

16 -40mL -35mL -30mL -25mL -20mL -15mL -10mL -5mL

17 -40mL -35mL -30mL -25mL -20mL -15mL -10mL -5mL 3. Note difference in water level

18 The water level changed 15mL We can say the rock displaced 15mL of water -40mL -35mL -30mL -25mL -20mL -15mL -10mL -5mL 35 mL -20 mL 15 mL

19 But wait, it gets better! -40mL -35mL -30mL -25mL -20mL -15mL -10mL -5mL

20 Volume of our rock…
