Solving a Hard Math Question: Volume of Concentrated Orange Juice

[DB]

in my opinion, i find this question really hard.

-the volume of a can of concentrated orange juice is represented by the following expression:
$$(8x^3-54x+54)\pi$$cm^3
the juice is prepared by emptying the concentrate into a large container and by adding 3 cans of the same volume of water. after a good stir, the juice is poured into glasses measuring 9 cm in height and whose radius is (2x-3) cm. Use a simplified algebraic expression to represent the number of glasses that can be filled up to 1 cm from the rim.

i've drawn my diagrams i just don't know where to start. any help would be apreciated...
thanks in advance

The volume of the large container is 4*volume of oj concentrate

you would then divide that by the volume of the glass (-1 cm of height)

o i see wat the question ment when it said "3 cans of water of the same volume" AS THE CONCENTRATE, its really badly written... thanks tho

btw, you won't find a constant number, you will find a function of x
