Which of the following is a derived unit?
a. meter (m)
b. second (s)
c. kilogram (kg)
d. mass density (kg/m^3)

Option D

Explanation:

From the options given above, only Density (kg/m^3) is a derived unit and the rest are fundamental unit.

A derived unit is obtained by combining two or more fundamental units together. For Density, we can obtain the unit as follow:

Density = Mass /volume

The unit of mass is Kg and that of volume is m^3

We can thus write the unit of destiny as:

Density => Kg/m^3
