Question

1.Zamienić 222kg/m3 na g/cm3. 2.Zamienić 10 kg/m3 na kg/dm3.

Answer 1

1kg = 1000g
1m^3 = (10dm)^3 = 1000dm^3

1dm^3= (10cm)^3 = 1000cm^3

222kg/m^3 = 222*1000g / 1000000cm^3 = 0,222g/cm^3
10kg/m^3 = 10kg / 1000dm^3 = 0,01kg/dm^3 

Answer 2

1.Zamienić 222kg/m3 na g/cm3

 

1 kg to 1000 g

1 m³ to 1 000 000 cm³

 

222 kg/m³ = 222 (1 000 /1 000 000) g/cm³ = 0,222 g/cm³

 

2.Zamienić 10 kg/m3 na kg/dm3.            

 

1 m³ to 1 000 dm³

 

10 kg/m³ = 10 kg/1 000 dm³ = 0,01 kg/dm³
