Let x = your number.
6x = x^2 - 27. Subtract 6x from each side.
0 = x^2 - 6x - 27. Factor
0 = (x-9) (x+3). Set each term equal to zero
(x+3) = 0. Subtract 3 from each side.
x = -3. This is the negative solution.
(x-9) = 0. Add 9 to each side.
x = 9. This is the positive solution.

A clock is 12 hours.
11 hours and 38 minutes is 22 minutes short of being a full 12 hours.
In 12 hours the time would be 5:35 again, so now subtract 22 minutes from the time:
5:35 - 22 minutes = 5:13
In 11 hours and 38 minutes, the time will be 5:13

Answer:
The least amount of dimensions would be using a 4ft x 4ft base.
Step-by-step explanation:
When looking to maximize area and minimize materials, a perfect square always does this. To prove the point, consider the 4 x 4 box in the answer to say a 16 x 1 box, which would have the same area.
The 4 x 4 box would have 4 sides each of 4 ft. Therefore, it would have 16 feet of sides to construct.
Meanwhile, there would be two sides on the other one that were 16 ft alone.
