If there was 10 cm of rain over one-hectare field, what is the total volume (in cubic meters) of rain over the field?

Correct option is D

Given:
Rainfall = 10 cm
Area of the field = 1 hectare = 10,000 m²
Required: Total volume of rain in cubic meters

Formula Used:
Volume of rain:

​$$\text{Volume} = \text{Area} \times \text{Height}$$

Solution:

$$10 \, \text{cm} = \frac{10}{100} = 0.1 \, \text{m}$$

$$\text{Volume} = 10000 \, \text{m}^2 \times 0.1 \, \text{m} = 1000 \, \text{m}^3$$

​​Final Answer: (D) 1000
