Question

ro=2050 kg/m³ L=20m l=10m h=2m m(masa)=?​

Answer 1

Răspuns:

densitate = masa / volum

masa = densitate x volum

V = L x l x h

V = 20 x 10 x 2 = 400 m³

masa = 2050 x 400 =  820 000 kg

Answer 2

V paralelipiped=L*l*h

V paralelipiped=20 m*10 m*2 m=400 m3

ρ=m/V

2050 Kg/m3=m/400 m3

m=2050 Kg/m3*400 m3=820000 Kg (m3 cu m3 se simplifica)

Succes!
