45dm2=

b) 1cm = 100mm więc 1cm2 = ( )2 =
72cm2 = 72 .
24cm2=

c) 1dm = 100mm , więc 1dm2 = ( )2=
0,26dm2 = 0,26 .
0,18dm2 =

d) 1km =1000m, więc 1km2 = ( )2=
0,5km2 = 0,5 .
0,8km2 =

e) 1m = 100cm, więc 1m2 = ( )2=
1,8dm2 = 1,8 .
7,3dm2=

2 Uzupełnij zapis wg wzoru :
WZÓR; 1m = 100cm, więc 1m3 =
= (100cm)3 100 00 00cm3
4m3 =4 . 1000000cm3 = 4000000cm3

a) 1dm = 10cm więc 1dm3 = ( )3 =
21dm3 = 21 .
95dm3

b) 1cm= 10mm, więc 1cm3 = ( )3 =
37cm2 = 37 .

Answer 1

a)  1dm =10cm, więc 1dm2 = ( 10 cm )2= 100 cm2
      35dm2 = 35   . 100cm2 = 3500cm2
       45dm2= 45. 100cm2 = 4500cm2

b)  1cm = 10mm więc 1cm2 =  ( 10 mm  )2 =100mm2
      72cm2 = 72   .100mm2 = 7200mm2
       24cm2= 24. 100mm2 = 2400mm2

c)   1dm = 100mm , więc 1dm2 = (100mm   )2= 10000mm2
     0,26dm2 = 0,26   . 10000mm2=2600mm2
     0,18dm2 =0,18. 10000mm2 = 1800mm2

d)  1km =1000m, więc 1km2 =   (1000m    )2= 1000000m2
      0,5km2 = 0,5   . 1000000m2 = 500000m2
      0,8km2 = 0,8, 1000000m2 = 800000m2

e)  1m = 100cm, więc 1m2 = ( 10000  )2= 10000cm2
     1,8dm2 = 1,8   .10000cm2 = 18000cm2
    7,3dm2= 7,3. 10000cm2 = 73000cm2

2.

a) 1dm = 10cm więc 1dm3 = ( 10cm   )3 = 1000 cm3
     21dm3 = 21   .1000 cm3 = 21000cm3
     95dm3 =95 . 1000 cm3 = 95000cm3

 b)  1cm= 10mm, więc 1cm3 = ( 10mm   )3 =1000mm3
        37cm2  = 37   . 1000mm3 =  37000mm3
        42cm2  =42 . 1000mm3 = 42000mm3
