.
The water level in a graduated cylinder stands at 31.0 mL before
and at 38.2 mL after a 20.54g metal bolt is submerged in the water.
What is the volume of the bolt?
What is the density of the bolt?
~~~~~~~~~~~~~~~~ 

The volume of the bolt is the difference of occupied volumes after and before submerging

    volume of the bolt = 38.2 - 31.0 = 7.2 cubic centimeters.


The density of the bolt is the ratio mass%2Fvolume = 20.54%2F7.2 = 2.85 g/cm^3.

Solved.
