<span>You are under contract to design a storage building with a square base and a volume of 12000 cubic feet. the cost of materials is $4 per square foot for the floor, $18 per square foot for the walls and $6 per square foot for the roof. find the width of the square base that minimizes the cost of materials.

To compute the slope of a segment, given its endpoints 
, you write
Given this formula, you have the four slopes:
Now, two segments are parallel if they have the same slope. So, AB and CD are parallel, because they both have slope 1, but BC and DA are not parallel.
This means that ABCD is not a parallelogram, because in parallelograms the opposite sides are parallel.
-14 < v - 11 ≤ - 7
Add 11 to both sides:
-3 < v ≤ 4
