Question 1199744
.


This problem was posted to the forum once earlier under this link 


https://www.algebra.com/algebra/homework/Volume/Volume.faq.question.1199456.html


with the diagram,  but even with the diagram the input was incomplete
and the solution was not possible, as I informed the source.



So due to some  (unknown to me)  reasons,  this  " problem "  is heavily sick/wrong/defective, 

as it often happens at this forum  (several times every day),  and it needs a thorough revision.
