Question

Roland is measuring a physical property of an object. He records the measurements: 3.12g/cm^3. Roland was most likely measuring which of the following:
A. Volume
B. Weight
C. Density
D. Mass

Answer 1

The correct answer is Volume!

Answer 2

Answer:   C. Density

Roland was most probably measuring density.

Explanation:

The measurement given in the question is $3.12 g/cm^3$. In The unit of the measurement g is the unit of mass and $cm^3$ is the unit of volume. Ratio of mass to volume gives an object’s density.

Hence $g/cm^3$ is the unit of density. Density has other units as well.  

Density of liquids is a crucial factor in fluid mechanics. Difference in densities of an object and a fluid determines whether that object will float or sink in that liquid. When two different liquids are mixed the liquid which has lesser density will form a layer above the denser liquid.
