How do you measure the volume of a liquid using water displacement?
With a graduated cylinder
Volume of object and water - volume of water = volume of the object

How do you measure the volume of a density block using Water Displacement?
Fill a graduated cylinder with water. Record the volume. Put the density block into the graduated cylinder. Record the new volume.
Volume of block and water - volume of water = volume of block
