Cube side lengths are all the same. I'm guessing y is one of the sides. To get the surface area you do length X width X 6 (since there are 6 sides).firstly we need to divide 96 by 6. That is 16. Then we divide it by 2 because the length and width are the same. This is 8. The length of one side must be 8m.

The formula for finding the surface area of a cube is A=6y^2 where y is the side length. we know a=96. so we just isolate y.
96/6= 6y^2 / 6
16=y^2
sqrt (16) = sqrt(y^2)
4=y

So y is 4

The number which could be added to both sides of the equation to complete the square is; -2.25.

<h3>Which number could be added to both sides of this quadratic equation to complete the square?</h3>

The quadratic equations give in the task content is; 1=x²-3x. Hence, to express the equation by completing the square method; we have;

1 - 2.25 = (x -3/2)² - 2.25

Hence, the number which should be added to both sides of the equation is; -2.25.
