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.

Edge of Cubical tank
= 20 cm
= 20 (0.01 m)……………..1 meter = 100 cm
= 0.2 m
Volume of Tank
= ( Edge ) ^ 3
= ( 0.2 m ) ^3
= 0.008 m^3
= 8 liters…………….. 1 m^3 = 1000 Liters
Volume required to fill the tank
= 8 - 3.75
= 4.25 Liters
