The density of wood is 0.65 g/cm³ in the CGS system. Its density in the SI system will be _______________.

Choose the correct option.

• Density is defined as mass per unit volume and its SI unit is kg/m³.
• 1 g/cm³  = 1000 kg/m³ 
• 0.65 g/cm³= 0.65 x 1000 kg/m³  = 650 kg/m³ 

The density of wood in the SI system will be 650 kg/m³.
