उत्तर
A smaller unit of volume is cubic centimetre (symbol cm3) and cubic decimetre (symbol 1 dm3). One cubic centimetre is the volume of a cube of each side 1 centimetre, i.e.,
1 cm3 = 1 cm × 1 cm × 1 cm.
Relationship between m3 and cm3
1 m3 = 1 m × 1 m × 1 m
= 100 cm × 100 cm × 100 cm
= 10,00,000 cm3 = 106 cm3.
Relationship between m3 and dm3
1 m3 = 1 m × 1 m × 1 m .
= 10 dm × 10 dm × 10 dm
= 1000 dm
= 103 dm
Note 1 m = 10 dm
