fluid mechanics density problem

velocityay

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
[tex]\rho[/tex]=m/v
Fg=[tex]\rho[/tex]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

Find the area of the base.
Volume of the column = Area* height.
Density = mass /volume.
