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
