(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A steel tank of cross sectional area 3 m^{2}and height 16 m weighs 10,000 kg and is open at the top. We want to float it in the ocean so that it is positioned 10 m straight down by pouring concrete into its bottom. How much concrete should we use?

2. Relevant equations

3. The attempt at a solution

I have thought about Potential gravity. I have looked that Waters density is 997 kg/m^{3}. I got this container's ensity (It is 208.33) but I just don't know how to solve it! :) I don't remember much about buoyancy and Bouyancy might be the thing needed here!

Answer is 19910 kg.....Please help! :)
