(w-2)^2 = 63
FOIL left hand side:
(w-2)^2 = w^2 - 4w + 4
So,
w^2 - 4w + 4 = 63
w^2 - 4w - 59 = 0
Then use quadratic equation to get values of w = 2 + 3*root(7) and w = 2 - 3*root(7).

First, let's find the area of one face of the cube.
Area = base x height
A = 5 x 5 = 25
There are 6 faces on a cube, so we can multiply the area of one face by 6 to get the total surface area.
SA = 25 x 6 = 150 ft^2
Hope this helps!
