Question

The Density of copper is 7.9 g cm³ . what will be the density in kg m³.
​

Answer 1

Given,

Density of copper=7.9g/cm³

To Find,

Density in kg/m³

Solution,

We have to convert g/cm³ to kg/m³

So we have to multiply it by 1000

As 1g/cm³=1000kg/m³

So 7.9g/cm³=7.9×1000

                      =790kg/m³

Hence, density in kg/m³ will be 790kg/m³.
