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 |

@dhaneshwari
cu in problem means cubic (i.e. X^3=x*x*x)...
cu in problem means cubic (i.e. X^3=x*x*x)...

1 hector is 10, 000 m2 1.5*10, 000.
0.05*15000.
0.05*15000.

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.

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.
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

Volume = (Length*Breadth)*Height.
= Area * Height.
= 15000*5/100.
= 750 m^3.
