  1. Giải đáp:
     21 m3 5 dm3 = 21,005 m3
    2,87 m3 = 2 m3 870 dm3
    5 m3 675 dm3 = 5,675 m3
    1996 dm3 = 1,996 m3
    2 m3 82 dm3 = 2,082 m3
    65 dm3 = 0,065 m3
    17,3m3 =17000 dm3 3000000 cm3
    82345cm3= 8dm3 2345cm3
    4 dm3 97 cm3 = 4,097 dm3
    5 dm3 6cm3 = 5,006 dm3
    2030 cm3 = 2,03 dm3
    105 cm3 = 0,105 dm3
     

  2. 21m3 5dm3=21 005 m3
