A cubical tank is filled with water to a level of 2 feet. If the water in the tank occupies 50 cubic feet, to what fraction of its capacity is the tank filled with water?  Choose the correct choice from the following
A) 1/3  B) 2/3  C) 3/4  D) 2/5  E) 5/6
The volume of water in the tank is H*L*B = 50 cubic feet.   Since H = 2, then L*B = 25 and L = B = 5.   Since the tank is cubical, the capacity of the tank is   5*5*5=
