Răspuns :
l = 4 cm
L = 10 cm
h = 2,5 cm
V = l * h * L = 10cm * 4cm * 2,5cm = 10cm * 10cm^2 = 100cm^3
m = 0.875 kg = 0.875 * 1000 = 875 g
P (ro) = m/V = 875g/100cm^3 = 8.75 g/cm^3
L = 10 cm
h = 2,5 cm
V = l * h * L = 10cm * 4cm * 2,5cm = 10cm * 10cm^2 = 100cm^3
m = 0.875 kg = 0.875 * 1000 = 875 g
P (ro) = m/V = 875g/100cm^3 = 8.75 g/cm^3
