Volume of two tanks
Having problems with this volume question.
There were 68000cm3 of water in tank X and tank Y. The heights of the water in both tanks are equal. Tank Y was 40% full of water. When all the water from tank Y was poured into tank X, 4litres of water overflowed.
A) find the height of the water in tank X at first?
B) find the capacity of tank Y?
Thanks in advance


Exactly .... It's like on the tip of my tongue ... but no matter what I have written down so far doesn't quite get there.
Base Area (BA)
We also know the Ratio of BAa : BAb is the same as the Ratio of the Volume A : B.
Also, for Capacity
X : Y
64 : B / .4
160 : B
So Y > 160/B x X
Y > 10240/B
And I think there is a mistake in here somewhere
Also,
The Base Area doesn't change so with a common Height,
64 : 2.5B is also the the same as BAa : BAb > A : B
A : B > 64 : 2.5B

i view this as two rectangular tanks with the same base areas.Tank y has a capacity of 170 liters and tank x 132liters.Tank y is simply taller
bjh

I don't believe this is feasible.
If the capacity of X : Y is 132 : 170
Then, the original volume of water in Y would be 170 x 40% = 68
This is the full amount of combined water. Thus the Height of the water in both Tanks, originally, would not be the same as indicated in the question.
