From 1 we have :

2 * l * b/min

From 2 we have :

h * l * b = 216

But we still can't get h ( or l*b), so answer is E.

l - length of base
h - height of base

Hi Bunuel,

Thank you for the explanation.
Just a query.. For this problem, would C be the answer if the tank was cube instead of rectangular?
