The volume of the tank is  6*12*18 = 1296 cubic meters.


It was 2/3 full water -- hence, the water volume was  %282%2F3%29%2A1296 = 864 cubic meters originally.


After adding 120 cubic meters of water, the water volume in the tank is

    864 + 120 = 984 cubic meters.


The percentage is  %28984%2F1296%29%2A100 = 75.93%.      ANSWER
