Question

You make the following measurements of an object: 42 kg and 22 m3.

What would the object’s density be? Show your work for credit and include final units.

Answer 1

The density of an object is defined as the ratio of its mass over its volume; it shows how much mass is packed in a specific volume unit. Mathematically, p=m/V where p=density.
Substituting, we get that:
`p= (42kg)/(22m^3)=1.91 (kg)/(m^3)`.
We have that the arithmetic value is 1.91 and the units are kg/m^3.
