The volume of the box is 1*2*5 = 10 m^3 = {{{10*(100^3)}}} cm^3 = {{{10^7}}} cm^3.


So, there are {{{10^7}}} small cubes 1x1x1 cm.


The height of this column will be  


    {{{10^7}}} cm = {{{10^7*10^(-2)}}} m = {{{10^5}}} m = {{{10^5*10^(-3)}}} km = {{{10^2}}} kilometers = 100 kilometers.   <U>ANSWER</U>
