The formula represents the surface area S of a cube with side lengths x.

S=6x^2

Solve for x.

To solve for x, you undo the multiplying by 6 by dividing by six on both sides. 6S=x^2. To undo X squared (x^2), you take the square root of both sides. So solving for X would give you The square root of 6S equals X. Without a number, there is no way to find a single value. It can be represented this way.
