A workshop grinds two solid lenses from the same uniform glass. Lens Q has one third of the mass of lens P. Which statement correctly compares the volume and density of lens Q with those of lens P?
Its volume is one third of the volume of lens P, and its density is one third of that of lens P.
Its volume is three times the volume of lens P, and its density is one third of that of lens P.
Its volume is three times the volume of lens P, and its density is the same as that of lens P.
Its volume is one third of the volume of lens P, and its density is the same as that of lens P.
