Answer:
Let a = side length of a cube
Let S = surface area of a cube
Area of a square = a²
Since a cube has 6 square sides: S = 6a²
To make a the subject:
S = 6a²
Divide both sides by 6:
Square root both sides:
(positive square root only as distance is positive)

Therefore,
for some constant a
Given the y-intercept is at (0, -5)
Substituting found value of a into the equation and simplifying:
