I figured I'd make a graphic.
When you say the thickness is 30 cm, do you mean the sides are 30 cm thick or would it be the cover?

The answer should be 628,000 liters,i dont know how they get the answer  i think its the sides

There are 1,000 liters in a cubic meter
Cylinder Volume = (1/4) * PI * (diameter)^2 * height
If we make a rough estimate, the diameter is about 10 meters.
Volume = (1/4 * PI * 100 * 10)
Volume is about 785 cubic meters or 785,000 liters.
If the answer is 628,000 liters then adjusting the diameter for the 30 cm thickness should give a more exact answer.
