D = kg/V = 2700kg/m^3.
5.4*10^-3 / V = 2700,
V = 5.4*10^-3 / 2.7*10^3 = 2*10^-6.
V = 0.05 * 0.02 * T = 2*10^-6,
1*10^-3*T = 2*10^-6,
T = 2*10^-6 / 1*10^-3 = 2*10^-3m = 2mm.
5.4*10^-3 / V = 2700,
V = 5.4*10^-3 / 2.7*10^3 = 2*10^-6.
V = 0.05 * 0.02 * T = 2*10^-6,
1*10^-3*T = 2*10^-6,
T = 2*10^-6 / 1*10^-3 = 2*10^-3m = 2mm.
