Answer 1

Step-by-step explanation

substance X will have least volume because it has maximum density and using the relation volume inversly propotional to the density of a substance.

substance Z will have least mass beacause it has least density and using relation mass is directly proportional to the volume of a substance .

substance Z will float in water because its density is less than the water (1 gm/cm^3).
