Đáp án`+`Giải thích các bước giải:

Ta có:

`1m^3 = 1000dm^3`

`1dm^3=1000cm^3`

`1cm^3 =1000mm^3`

`1)4m^3` `250dm^3 = 4 + 250/1000 = 4,25 m^3`

`2)15dm^3` `8cm^3 = 15 + 8/1000 = 15,008 dm^3`

`3)2m^3` `75dm^3 = 2 + 75/1000 = 2,075 m^3`

`4)0dm^3` `45cm^3=45/1000=0,045dm^3`

`5)12cm^3` `5mm^3=12+5/1000 =12,005 cm^3`

`6)8m^3` `5000cm^3 =8 + 5000/1000000=8,005 m^3`

`7)1m^3` `5dm^3=1+5/1000=1,005m^3`

`8)10dm^3` `10cm^3 = 10 + 10/1000 = 10,01 dm^3`

`9)45m^3` `7dm^3=45+ 7/1000 = 45,007 m^3` 

`10) 0m^3` `850cm^3 = 850/1000000 = 0,00085 m^3`
