Question

The density of aluminium is 2700 kg/cm3 what does it means? Calculate th density of aluminium in CGS system

Answer 1

The density of aluminium is 2700 kg/cm³ means the thickness of aluminium is 2700 kg/cm ³

ρ=2700⋅kg⋅m−3

=2700×103⋅g⋅(100⋅cm)−3

=2.700×106⋅g×11003⋅cm3

=2.700×106⋅g×10−6⋅cm−3

=2.700⋅g⋅cm−3

Answer 2

First of all, u have made a typo error. Density of Aluminium is 2700kg/m³
In simple words, it means that 1 m³ of aluminium weighs 2700 kg.
The CGS units of density is g/cm³.
2700 kg = 2700000g
1m³ = 1000000 cm³
Therefore the density is 2700000/1000000 g/cm³
⇒ Density of Al in CGS units = 2.7 g/cm³
I hope u have found this useful. Dont forget to mark this as brainliest answer!!
