Q.  Find the maximum volume 
      you can make from a square

L = 0 (slider from 0 to 5, step 0.1)
A: (0, L)
B: (10, L)
E: (L, 10)
F: (10 - L, 10)
G: (10 - L, 0)
H: (L, 0)
a = Segment(A, B)
C: (10, 10 - L)
b = Segment(C, B)
D: (0, 10 - L)
c = Segment(C, D)
d = Segment(D, A)
e = Segment(E, F)
f = Segment(F, G)
g = Segment(G, H)
h = Segment(H, E)
v: (((10 - (2 * L)) * (10 - (2 * L))) * L)
