A cubical tank is filled with water to a level of 3 feet. If the water in the tank occupies 75 cubic feet, to what fraction of its capacity is the tank filled with water? Select the correct option
A) 1/2
B) 2/3
C) 3/4
D) 2/5
E) 3/5
The volume of water in the tank is H*L*B = 75 cubic feet.   Since H = 3, then L*B = 25 and L = B = 5.   Since the tank is cubical, the capacity of the tank is   5*5*5=
