The volume of a cube is 975cm3. Work out the length of its side rounded to 1 DP.

Answer 1

Hello Riha,

If x is the side of a cube, then the volume of a cube is equal to

V = x³

So to find x, you would take the cubic root of volume: x = ³√V = ³√975

You would enter that in your calculator and round as the problem asks. That answer will be in centimeters.

If ³√975 is not easy to type on your calculator, you can try 975^(1/3). It will be the same answer.
