Question

In a shower 5 cm of rain falls. The volume of water that falls on 2 hectares of ground is

Answer 1

Answer:

volume of water = 1000 m³ = 1 megalitre

Step-by-step explanation:

1 ha = 100 m × 100 m = 10000 m²

Area = 2 ha = 20000 m²

Depth of water = 5cm = 0.05 m

Volume of water = area × depth

 = 20000 m² × 0.05 m

 = 1000 m³

1 litre = 0.1 m × 0.1 m × 0.1 m = 0.001 m³

1000 litres = 1 m³

So volume of water = 1000 × 1000 litres = 1000000 litres = 1 megalitre

Answer 2

Answer:

5 cm = 0.05 cm

1 hectare = 10,000 cm

so, 2 hectares = 20,000 cm

Volume of ground = (0.05*20,000)cm³

=1,000 cm³
