zad 1
1 g = 0,001 kg
1 cm³ = 0.000001 m³
19,30g/cm3 = (19,3 * 0,001)/0.000001 [kg/m³] = 19300 [kg/m³]
zad 2
810 kg/m3
0,81 g/cm3
1 g = 0,001 kg
1 cm³ = 0.000001 m³
19,30g/cm3 = (19,3 * 0,001)/0.000001 [kg/m³] = 19300 [kg/m³]
zad 2
810 kg/m3
0,81 g/cm3
1. 19,30 g/cm3 = 19,30 x 1000kg: 1000000m3 =1930000kg:1000000m3= 1,93kg/m3
2.810kg/m3 = 810 x 1/1000g : 1/ 1000000cm3 = 0,81g:1/1000000cm3=810000g/cm3
2.810kg/m3 = 810 x 1/1000g : 1/ 1000000cm3 = 0,81g:1/1000000cm3=810000g/cm3
1) 19.3g/cm3=19,3 x 0,001kg/0,000001m3=19300kg/m3
2)810kg/m3=810 x 1000g/1000000cm3=0,81g/cm3
2)810kg/m3=810 x 1000g/1000000cm3=0,81g/cm3
