Let call the height of the space that doesn't contain water is x

First we must find the volume of the aquarium:
50 * 30 * 40 = 60000 cm^3
The volume of the space that doesn't contain water :
60000-12000 = 48000 cm^3
The height of the space:
50 * 30 * x = 48000 cm^3
=> x = 48000/(50*30) = 32
The height of the water:
the height of the aquarium - x = 40 -32 = 8cm

Total volume of water = 12 liters = 12 x 1000 cm3
The base of the aquarium is 50 x 30 = 1500cm2
Base of tank x height of water = volume of water
1500 x height = 12000; height = 12000 / 1500 = 8
