Answer:
Maximum Volume = 29,659.5 cubic inches
Step-by-step explanation:
We can write the perimeter as 2*(x+h) and this is equal to 117
So

The volume is 
Plugging the expression for h, we have:

The max volume can be found when this differentiated is equal to 0, or dV/dx=0

x can't be 0, so we take x = 39
and thus h=58.5-x = 58.5-39=19.5
Max Volume = 
There were 64 ducks in the beginning
Step-by-step explanation:
-9 x s = 6
-9 x 6 =s
-54=s
s=-54
