Question

The S.I. unit of density is _____.

• A. $g/m^3$
• B. $kg/m$
• C. $kg/m^3$
• D. $kg/m^2$

Answer 1

The correct option is C $kg/m^3$

Density is defined as the mass per unit volume of a substance.
$\text{Density}$ = $\text{Mass}÷\text{Volume}$
S.I. unit of mass is kg and that of volume is $m^3$.
Hence, S.I. unit of density is $kg/m^3$.
