Question

un corp din aluminiu are masa de 300g.care este volumul sau.

Answer 1

m=300g
d=2700kg/m3
V=?

$d= \frac{m}{V}= \frac{V}{0,3}=2700$
v=0.3x2700=810cm3=0.810m3
R.: 0.810m3

Answer 2

m=300g
v=?
d=2700kg/m3

Densitate=masa/volum .
Vomul=masa * densitate .

d=m/v=v/0.3kg=2700
v=0.3 x 2700= 810 cm3 = 0.810m3
x inseamna INMULTIT .
