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 |

The volume of water that falls on 1.5 hectares(area) of ground
Conversion
{
1 hectare = 10,000 m^2.
So, Area = (1.5 x 10000) m^2 = 15000 m^2. //converting into meters.
}
5 cm of rain falls -- Depth(height) of the water from ground level.
Depth(height) = 5 cm = 5/100 m
Finding Volume
Considering/assuming ground as cuboid.
Volume = (Length*Breadth)*Height.
= Area * Height.
= 15000*5/100.
= 750 m^3.

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

If the rain is falling vertically.
And the area covered is base then it's forming a right angle tri angle,
So we know v=length * breadth * height.
Also, that length*breadth = area.
So,
V = 15000 * 0.05,
So, v = 750.

5 cm of rain falls means height of the water from the ground so depth is 5 cm and which must be converted into meters because volume should be measured in m^3.

How can I recognised that volume = area * depth and depth from where found please give me the answer if anybody know?

In a shower, 5 centimetres of rainfall find the volume of water that falls on 2 hectares of land.
Find the answer.
Find the answer.

Height is taken 5cm, because the flow rate is assumed constant over the entire surface on which the rain falls.

How to calculate depth? By using which formula I am not getting that method. Can anyone explain me?

Please can you tell me. What is meant by xcm of rainfall and how you calculated depth?
