Question

Un bazin are forma unui paralelipiped dreptunghic ABCDA'B'C'D'.Se cunosc AB=16m,BC=4m,AA'=3m.
a)in bazin se afla 128000 litri de apa. Calculati inaltimea la care se ridica apa in bazin.

Answer 1

Vapa=ABxBCxh=128000 l
128000l=128000dam3=128m3
rezulta ca 16x4xh=128
de aici rezulta h=2m

Answer 2

V=L*l*h

V=16*4*3=192 m³= 192 000dm³
1dm³=1l
V=192 000l

192 000-128 000=64 000l

V=64 000l=64 000dm³=  64m³

V=L*l*h
V=16*4*h=64

h=64:64
h=1m
