The maximum width must be 
Step-by-step explanation:
Let
L ----> the length of the rectangular pool
W ---> The width of the rectangular pool
we know that

so
----> inequality A
we have

substitute the value of L in the inequality A

simplify



The maximum width must be 
<span>πn < x < </span>π + <span>π<span>n
</span>In interval notation: (</span><span>πn, </span>π + <span>π<em>n</em>)</span><span>
</span>
The answer is: 562.4
The volume of a rectangle can be found by doing length*width*height
Or
9.5*7.4*8 which equals 562.4
