Question

Density of an object is 1.8g/cm3. express it in kg/m3

Answer 1

1 kg = 1000 g

1 g = 1/1000 kg = 0.001 kg

1 m = 100 cm

1 cm = 0.01 m

1 cm3 = 0.01 x 0.01 x 0.01 m3

1 cm3 = 0.000001 m3

1.8 g/cm3 = 1.8 x 1 g/cm3

1 g/cm3 = 0.001/0.000001 kg/m3 = 100 kg/m3

1.8 g/cm3 = 180 kg/m3

Answer 2

1gm/cm3 = 1000kg/m3

1.8gm/cm3= 1800kg/m3
