Question 106613: Can you help with this please.

The volume of a cube is given by V = s^3, where s is the length of a side. Find the length of a side of a cube if the volume is 800 cm3. Round the answer to three decimal places.
I got this 800*800*800=s*s*s so 5.120=s
Thank You

You have the right idea, but I'm not sure where you got from.

Start with the given equation

Take the cube root of both sides. This will undo the exponent of 3

Take the cube root of to get
Take the cube root of 800 to get 9.283

So the side length is

s = cube rt (800)
s = [cube rt (8)]
s = 2
or
s = 9.283177...

You can check your answer by cubing 5.12
so that can't be correct, can it? You want the answer to be 800 as in:
or
What you have to do is to find the cube root of 800 whcih can be done on any good calculator.
to the nearest thousandth.
s = 9.283 cm.
