## Answer :

1000 cubic cm = 1 liter

V=WHL

2000 cubic cm=W(20)(25)

2000 cubic cm=W(500)

2000/500 = 4

depth = 4cm

V=WHL

2000 cubic cm=W(20)(25)

2000 cubic cm=W(500)

2000/500 = 4

depth = 4cm

thus, 2 litre = 2000cm³

volume = lbh

2000cm³ = 25 x 20 x h

2000cm³ = 500 x h

Thus, h = 4 cm.

Thus, the depth of tank is 4 cm
