A student finds a figurine that looks like silver. He wants to find out if the figurine is pure silver. Density of silver is 10.5g/cm cubed. The figurine weighs 300g. He drops the figurine into a graduated cylinder of radius 4cm. The water level rose 1.5cm. Is the figurine pure silver, justify your answer. Is the material of the figurine heavier or lighter per cm than silver.
Hint: Volume of water displaced is equal to the volume of the object submersed.
