Volume is defined as the amount of space that an object occupied. It is measured in [tex]m^3[/tex]
Density is defined as the ratio of an object's mass and volume. It is measured in [tex]kg/m^3[/tex]
[tex]\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}[/tex]
Gravity is defined as the force that attracts the body to the center of the earth. It is measured in Newtons.
Hence, the correct answer is Volume.
