The volume of a cube is given by V = s3. Find the length of a side of a cube if the Volume is 729 cm3. It would be three times it's self.

The formula for the Volume of a cube = s * s * s
= s^3
which means that when V = 729
729 = s^3
s = (cube root) 729
= 9 cm

729 cm^3 = s^3
Take the cube root of both sides
cuberoot 729 = cuberoot s
9 = s
s = 9 cm

9 is correct.
Oh and by the way...the correct word is "its", not "it's". The only time you should use the contraction is when you mean "it is".
Just FYI.

V = sss.
Volume is 729cm(cm)cm.
The "s" in "it's" is short for "his"
