Question 72552
In order to solve for s (the side), just take the cube root of 729.
{{{V=s^3}}}
{{{729=s^3}}}
{{{3sqrt(729)=3sqrt(s^3)}}}Solve for s by taking the cube root of both sides (this undoes the exponent of 3)Note: the 3 in front of the root should be higher signifying its a cube root.
{{{s=9}}}So the side's length is 9 cm
Check:
If you multiply 9 by itself 3 times (to find the volume) you'll get 729
{{{(9)^3=729}}}Answer works
