If a river basin has an area of 2000 km² and receives an average rainfall of 800 mm per year, what is the total volume of water received by the basin in cubic meters? (2000)
Step 1: Understand the area of the river basin, which is given as 2000 km².
Step 2: Convert the area from square kilometers to square meters. Since 1 km² = 1,000,000 m², multiply 2000 km² by 1,000,000. This gives you 2000 × 1,000,000 = 2,000,000,000 m².
Step 3: Understand the average rainfall, which is given as 800 mm. Convert this to meters. Since 1000 mm = 1 m, divide 800 mm by 1000. This gives you 800 / 1000 = 0.8 m.
Step 4: Calculate the total volume of water received by the basin using the formula: Volume = Area × Rainfall. Substitute the values: Volume = 2,000,000,000 m² × 0.8 m.
