An irregular shaped object was placed in a graduated cylinder. The initial volume was 50mL. The final volume was 75mL.

What is the volume of the irregular shaped object?

• 25mL

• 75mL

• 50mL

How do you find the volume of irregular shaped object?

• length (l) x width (w) x height (h)

• Water displacement

• Measure its mass using a scale

Select the true ststement.

Look at this image.  Which object has the LOWEST density in water?

How do you know? 

• The Ping Pong Ball because it floats to the top. 

• The bolt because it has sunk to the bottom.

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 g/cm³
• 28 g/cm³
• 1/7 g/cm³

If an object has a density of 3.6 g/mL and you put it into water, will it sink or float?
