A, B, and C are three unequal faces of a rectangular tank. The tank contains a certain amount of water. When the tank is based on the face A, the height of the water is half the height of the tank. The dimensions of the side B are 3 ft × 4 ft and the dimensions of side C are 4 ft × 5 ft. What is the measure of the height of the water in the tank in feet?
(A) 2
(B) 2.5
(C) 3
(D) 4
(E) 5
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.
