1.Cantitatea de apa necesara umplerii unui bazin cu dimnsiunile de 2dm,10cm si 1,4 metrii este egala cu.... litri
2.Daca 1 metru de cablu cantareste 200g atunci 1,2 km de cablu vor cantari ...kg

Answer 1

1) L*l*h=2*1*14=28dm^3=28litri
10cm=1dm
1,4m=14dm
1dm^3=1l
2)1m.....200g
1200m....x

x=1200*200:1=240000=240kg

Answer 2

V=2dm*10cm*1.4m=2dm*1dm*14dm=28dm³=28 litri

1.2km(1200m).............x
1m..............................200g(0.2kg)
x=1200*0.2=240 kg
