1) The mass of the object is 18 g
2) The correct relationship is option C
What is density?
Density is the ratio of the mass to the volume of a body. We know that the density of the body is an intrinsic property. This implies that it does not change with the amount of substance or with the mass of the body. Let us now try to solve each of the problems.
1) Density = mass/volume
Volume = 1 cm * 3 m * 2 cm = 6 cm^3
Density of the body = 3 g/cm^3
Mass of the body = 6 cm^3 * 3 g/cm^3 = 18 g
2) To answer question 2, we have to remind ourselves of what we said that the density is the ratio of the mass to the volume of a body and that the density of a body is constant. This implies that the relationship that defines the relationship of the mass to the density of the material does not change and this is shown by option C.
