2.Calculati volumul uni paralipiped dreptunghic cu urmatoarele dimensiuni:
a)L=12 cm,l=6 cm,h=10 cm;
b)L=20 dm,l=15 dm,h=10 dm;
c)L=2 dam,l=1,5 dam,h=1,8 dam;
d)L=3,2 m,l=0,5 m,h=2 m;
e)L=1,8 cm,l=0,4 cm,h=1,5 cm

Answer 1

Vcub=3la puterea3=27cm^3
Vcub=10^3=100dm^3
Vcub=24^3=13824dam^3
Vcub=1,5^3=3,375m^3
Vcub=0,8^3=0,512km^3
Vcub=0,13^3=0,002197
Vp=L•l•h=12•6•10=720cm^3
Vp=20•15•10=3000dm^3
Vp=2•1,5•1,8=5,4dam^3
Vp=3,2•1,5•2=3,2m^3
Vp=1,8•0,4•1,5=1,08cm^3
