A cubical tank is filled with water to a level of 3 feet. If the water in the tank occupies 48 cubic feet, to what fraction of its capacity is the tank filled with water? Pick:
A) 1/2 B) 2/3 C) 3/4 D) 4/5 E) 5/6
The volume of water in the tank is H*L*B = 48 cubic feet.   Since H = 3, then L*B = 16 and L = B = 4.   Since the tank is cubical, the capacity of the tank is   4*4*4=
