Question 24890
Oops!!  I think the previous solution is in error!  The formula for Volume is {{{V= s^3}}}, so 

{{{s^3 = 729}}}.


To solve this, you'll need to take the cube root of each side.  A calculator would be helpful, since this number 729 is fairly large.  If you don't have a calculator, then what you will need to do is find a number that you can cube (that is, multiply times itself and times itself again!) and get 729.  You probably know that {{{5^3= 125}}}, and {{{10^3 = 1000}}}.  Since 729 is between 125 and 1000, the number you need must be between 5 and 10.  


Try 9!  {{{9^3 = 729}}}, so the answer is s= 9 cm.
