Question

Vă rog vreau rezolvata!!!

Answer 1

volumul paralelipipedului=Vp=Lxlxh=3x2x2,5=15 m³=15000litri=150hl

timpul in care se va umple bazinul=150/7,5=20 ore

Answer 2

V=l*L*h;

V=3*2*2,5=15(m³)=15000(dm³)=15000 litri(L);

7,5hl=750L deoarece 1hl=100L;

750L-----1 ora

15000L-----x ore

x=15000*1/75

x=20 ore se va umple bazinul.

Bafta!
