The given parameters;

Mass of sample X = 40 g

Initial volume of water before the sample was placed = 14 ml

Final volume of water after the sample was placed = 19 ml

The volume sample X is the increase in the volume of water after it was placed in the cylinder.

Volume of sample X = 19 ml - 14 ml = 5 ml

Mass of sample of X = 40 g

The density is obtained by dividing the mass of sample X by its volume as shown below;

density = mass/volume = 40/5 = 8

Thus, the density sample X is 8 g/ml.
