900000 litres

The correct answer is 900000 litres — Convert cubic metres to litres: $900 \times 1000 = 900000 litres$ .

Step-by-step solution

Compute the volume in cubic metres using $V = l \times w \times d$ : $30 \times 15 \times 2 = 900 m^{3}$ .
Convert cubic metres to litres: $900 \times 1000 = 900000 litres$ .

Common mistake: Forgetting to convert to litres
