Question

The density of Brass is 8.4 g/cm3 in CGS system. Find its value in SI system.​

Answer 1

Density of brass in CGS system=8.4g/cm^3

We know

$\\ \sf\longmapsto 1kg=1000g$

$\\ \sf\longmapsto 1m^3=10000cm^3$

Now

$\\ \sf\longmapsto 1g/cm^3=\dfrac{\dfrac{1}{1000}}{\dfrac{1}{10000}}$

$\\ \sf\longmapsto 1g/cm^3=\dfrac{1}{10}kg/m^3$

$\\ \sf\longmapsto 1g/cm^3=0.1kg/m^3$

Thus

$\\ \sf\longmapsto 8.4g/cm^3=8.4\times 0.1$

$\\ \sf\longmapsto 8.4g/cm^3=0.84kg/m^3$
