Calculate the mass of a 3cm cube of aluminium.
I think the question is based on the previous that was in my book. It said: a 2cm cube of aluminium has mass 21.6g. It's density is 2.7g/cm<cubed>

The problem is: I should calculate the mass of a 3cm cube of aluminium. Previously, there was a question saying: A 2cm cube of aluminium has mass 21.6g. Calculate the density of aluminium in g/cm<cubed> and so I think that it is associated with the question I am asking.. but I don't know how should I calculate the mass, if I don't know the density??
