If the depth of a river increases by 2 m and the width remains constant, how does this affect the volume of water if the length of the river is 1000 m? (2019)
Step 1: Understand the formula for volume, which is Volume = Length × Width × Depth.
Step 2: Identify the given values: Length of the river = 1000 m, Depth increase = 2 m, Width remains constant.
Step 3: Since the width is constant, we can focus on how the depth change affects the volume.
Step 4: Calculate the increase in volume due to the depth increase: Volume increase = Length × Width × Increase in Depth.
Step 5: Substitute the known values into the formula: Volume increase = 1000 m × Width × 2 m.
Step 6: This simplifies to Volume increase = 2000 m³ (since Width is constant and we are calculating the increase).
