Answer:
As the tank is cubical,hence its volume must be L^3
L=20cm=0.2m
Total volume=0.2^3=0.008m^3=8 Litres.
Initially it is filled with 3.75Litres=0.00375m^3
Hence,the total volume of water which can be filled is=0.008–0.00375=0.00425m^3
Hence,4.25 Litres of water is required to fill the tank completely.
