The masss of 4m^(3) of iron is 31200 kg....

The masss of `4m^(3)` of iron is 31200 kg. calculate the density of iron in SI unit.

Text Solution

Verified by Experts

`because`Density`=("Mass")/("Volume")` [here, mass=31200 kg, volume `=4m^(3)`]
`=(31200)/(4)kg//m^(3)=7800kg//m^(3)`.
`therefore`Density of iron`=7800kg//m^(3)`.
