--Calculate the density rho1 of the aluminum block using equation (3) in the lab manual:
--Calculate the density rho2 of the aluminum block directly using rho = m/v, where m is the mass of the object and V is the volume of the displaced water:
--Compare the average of these two calculated values of aluminum density with the known one, rhoAl = 2.7 g/cm3:
