(D) 4

(E) 5


After resting face A as the base of the water tank, since 4 ft is common to both the faces B and C; 4 ft must be the measure of height of the tank.
So, the height of water=\(\frac{4}{2}=2\)
Ans. (A)

A, B, and C are three unequal faces of a rectangular tank ==> L!=B!=H
As on A the tank bases.... the common side of plane B & C will be the height of the Tank. i.e= H=4 ( ref pic: Water Tank)
Thus height of water in tank is 4/2 ft or 2 ft....................Ans A.
