Question 866561
Use the density of sodium. This must be given with the question or you need to look in a reference source.   What is, also, the identity, if known, of this "nonreactive liquid"?


If you know the density, d, of sodium and unit is grams per cubic centimeter, then {{{145.5*g(1/d)(cm^3/g)=(145.5/d)*cm^3}}}, the volume of this sodium.


This volume must conform to:
Let h = height change in the cubical container corresponding to the sodium
{{{highlight_green145.5/d=h*10*10)}}} and solve this for h.
{{{highlight(h=145.5/(d*100))}}} cm.
