Explanation:
1. (i) As 1m = 100cm. so 1m^2 = 10000cm^2
= 15m^2 = 150000cm^2
(ii) 1m^3 = 1000000cm^3
= 5m^3 = 5000000cm^3
2. (i) to convert kg/m^3 to g/cm^3 we divide it by 1000
850 kg/m^3 = 850/1000 = 0.85 g/cm^3
(ii) to convert g/cm^3 to kg/m^3 we multiply it by 1000
15.6 g/cm^3 = 15.6 × 1000 = 15600 kg/m^3
