Question

A bag of cotton weighs 20kg and occupies a volume of 5m3find the density in CGS units

Answer 1

Mass = 20 kg
1 kg = 1000 g
Mass = 20,000 g
Volume = 5 m³
1 m = 100 cm
Volume = 5$\times$100$\times$100$\times$100
= 5$\times$10⁶ cm³
​Density = Mass / Volume
= 20,000 / (5$\times$10⁶)
= 4$\times$10^-3 g cm^-3
= 0.004 g cm^-3
