Răspuns:
G(Al) = G(Pb) = 10 N
Greutatile fiind egale si g = constant => masele corpurilor sunt egale
G(Al) = m(Al)×g => m(Al) = G(Al)/g = 10N/(10N/kg) = 1 kg
G(Pb) = m(Pb)×g => m(Pb) = G(Pb)/g = 10N/(10N/kg) = 1 kg
d = m/V => V = m/d
V(Al) = 1000g/(2.7g/cm³) = 370.(370) cm³
V(Pb) = 1000g/(11.3g/cm³) = 88.495 cm³
