1234mm=.........m=.........hm=.......km

250m=....dm=......mm

3,2m³=..........dm³=.........cm³=.......cc

4,5m³=.....l=......ml

123 l =.......cm³=.......cc=........m³

3kg=.......g ; 4562kg=.....tạ=.......tấn

m=235kg thi P=.........N ; m=560g thì P=.........N

P=240N THI m=KG ;P=28N thi m=.......kg

chú ý: 1dm³=1l ; 1cm³=1cc ; 1cm³=1ml=1cc

Answer 1

2,5 km= 2500 m= 250000 cm

1234mm= 1,234 m= 0,1234 hm= 0,01234 km

250m= 2500 dm= 250000 mm

3,2m3= 3200 dm3= 3200000 cm3= 3200000 cc

4,5m3= 4500 l= 4500000 ml

123 l = 123000 cm3= 123000 cc= 0,123 m3

3kg= 3000 g ; 4562kg=45,62 tạ= 0,62 tấn

P=240N THI m= 24 KG ;P=28N thi m= 2,8 kg

m=235kg thi P= 2350 N ; m=560g thì P= 5,60 N

    

 

  

 

Answer 2

2,5km = 2500m = 250000cm

1234mm = 12,34m = 0,1234hm = 0,01234km

250m = 2500dm = 250000mm

3,2m\(^3\) = 3200dm\(^3\) = 3200000cm\(^3\) = 3200000cc

4,5m\(^3\) = 4500l = 4500000ml

123l = 123000cm\(^3\) = 123000cc = 0,123m\(^3\)

3kg = 3000g ; 4562kg = 45,62 tạ = 4,562 tấn

m =235kg thì p = 2350 N ; m = 560g thì p = 5,60 N

P = 240 N thì m = 24 kg ; p = 28 N thì m = 2,8 kg
