Assuming the given density of lead is in g/cm³, the density in kg/m³ is 30.2 × 10³ kg/m³. Let's find :-
Now,
The density of lead is given as 30.2, but to provide a unit conversion to kilograms per cubic meter (kg/m3), we must assume the original density is in grams per cubic centimeter (g/cm3) which is a common unit for density of solids.
To convert the density from g/cm3 to kg/m3, we use the conversion factors: 1 kg = 1000 g and 1 m3 = 106 cm3. Therefore, the density of lead in kg/m3 is 30.2 g/cm3 × 1000 kg/1000 g × 106 cm3/m3
which simplifies to 30.2 × 103 kg/m3.
