3.12 litres

Step-by-step explanation:

First find the volume of the tank:

Volume = B x H x L = 2 x 1.3 x 1.6 = 4.16m^3

Now, calculate the capacity:

1 m^3 = 1 litre

4.16 m ^3 = 4.16 litres.

Given That 1/4 of the Tank is already full, this means. 3/4 of its capacity is still needed.:

3/4 x 4.16 = 3.12 litres.

Hope thios helps.
