Answer 1

30 cm2 = 30*(m/100)^2 = 30/10000 m2 = (3*10^-3) m^2 = 0,003 m2


25 g/cm3 = 25*(kg/1000) / (m/100)^3 = 25*10^3  kg/m3 = 25000 kg/m3


0,3 mm2 = 3*(10^-1)*(m/1000)^2 = 3*10^-7 m3


0,8 mg/mm3 = 8*(10^-1)*(kg/10^6) / (m/1000)^3 = 8*(10^-1)*(10^-6) / (10^-9) kg/m3 =

= 8*10^2 kg/m3 = 800  kg/m3
