Question

During a rainy day, 4 cm of rain falls. The volume (in m³) of water that falls on 1.5 hectares of ground is:
1. 600
2. 450
3. 750
4. 500

Answer 1

Correct Answer - Option 1 : 600

Given:

Rain fall = 4 cm

Volume of water = 1.5 hectares

Concept Used:

1 hectares = 10000 m²

Volume = Area × Depth

Calculation:

1.5 hectares = 15000 m²

Depth = 4cm = 1/25 m

Volume = Area × Depth

⇒ Volume = 15000 × (1/25) = 600

∴ Volume of water falls is 600 m³
