Question 254978
volume =L*w*h
They are tricking you by telling you the height of the aquarium. 
We don't care. We want the height of the water. But your answer h shouldn't be over 24 inches the height of the aquarium.

1584=22*12*h
(1584)/(22*12)=h
Solve for h
I hope there are no fish in it because there is very little water.
