Question

S.I unit of density is

• A. $\frac{kg}{m^3}$
• B. $\frac{kg}{m}$
• C. $\frac{kg}{m^2}$
• D. None of these

Answer 1

The correct option is A $\frac{kg}{m^3}$

The si unit of density is $\frac{kg}{m^3}$

Density is an SI derived unit. It is derived from the SI fundamental unit for mass, the kilogram, and the SI fundamental unit for length, the meter. Density is the mass per unit of volume. The SI derived unit for volume is cubic meters. So the derived SI unit for density

is $\frac{kg}{m^3}$

Hence option $A$ is a correct answer.
