 P: 5 1. The problem statement, all variables and given/known data If the density of iron is 7.8x103kg/m3, what is the highest possible height of a square based column of sides=40cm and mass of 1,000kg? 2. Relevant equations $$\rho$$=m/v Fg=$$\rho$$vg (I think?) 3. The attempt at a solution I took the length of the side of the square and used it to find a volume which I got to be .064m3, I'm really not sure where to go from here or if I understand what the question is asking
