Rita poured 20 cm^3 of water in a graduated cylinder. She dropped a piece of stone into it. The water level rose to 30 cm^3. What is the volume of the stone?

Sagot :

The process done is called the water displacement method. The volume of the item dropped is:
[tex]v_f-v_i[/tex]
We subtract the initial volume from the final volume to get the volume of the stone.
[tex]30cm^3-20cm^3=10cm^3[/tex]

Therefore the volume of the stone is [tex]10cm^3[/tex]
