Explicație pas cu pas:

4)   0.08hm=8m=80dm

     30 dam = 300m =3000dm

     1.2dam= 12m= 120dm

80*3000*120m = 28800000 litri

5) V cb = 3^3=27mc=27000litri

ng  =  27000/10 = 2700

6)  v = 12*10*5 = 600dmc =600l

ng = 600/10 = 60

7)  V cb = 10^3=1000cmc

    V vas =25*8*7 =1400cmc

h= 7/1.4= 5cm

8)   V vas=20*18*10=3600mc

V cb 40^3= 64000mc

H=40*3600/64000= 2.25 m
