In a shower, 5 cm of rain falls. The volume of water that falls on 1.5 hectares of ground is:
Answer: Option
Explanation:
1 hectare = 10,000 m2
So, Area = (1.5 x 10000) m2 = 15000 m2.
| Depth = | 5 | m | = | 1 | m. |
| 100 | 20 |
 Volume = (Area x Depth) = |
 |
15000 x | 1 |  m3 |
= 750 m3. |
| 20 |

How can we measure the rainfall?

After the rain falls on the ground, its height is measured. That is how the rainfal is generally measured.
now, coming to the problem, here, the height is 5cm = 5/100m.
volume=lbh
but area=lb
volume=area*h
hence, volume= 15000*5/100 =750
now, coming to the problem, here, the height is 5cm = 5/100m.
volume=lbh
but area=lb
volume=area*h
hence, volume= 15000*5/100 =750

1MT=100CM,SO
5CM=1/100M
5CM=1/100M
