  1. Finding VOLUME

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

  3. The OBJECTS

  4. The OBJECTS Let's try this one first!

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

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

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

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

  9. Volume = L x W x H = 6cm x 2cm x 4cm = 48cm3

  10. So, the VOLUME (the amount of space that this 3 dimensional object takes up) of this object is 48 cm3 Nice work.

  11. The OBJECTS Now, let's try this one

  12. Find VOLUME Can't do L x W x H it's an irregular shape. things that make you go hmmmm...

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

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

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

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

  19. But wait, it gets better! 3 1mL = 1cm -40mL -35mL -30mL -25mL -20mL -15mL -10mL -5mL so... 3 15mL = 15cm

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