Answer:
2.7 g/cm³ , 2700 kg/m³
Explanation:
Relative density = Density of substance / Density of water
From above,
Density of substance = Relative Density × Density of water
In SI units
Density of water = 1000 kg/m³
Density of Aluminium = 2.7 × 1000 kg/m³ = 2700 kg/m³
In CGS units
Density of water = 1 g/cm³
Density of Aluminium = 2.7 × 1 g/cm³ = 2.7 g/cm³
