Question

$200m^3$ of water is to be used to irrigate a rectangular field whose area is $1000m^2$. What should be the height of the water level in the field?

• A. 0.8
• B. 0.2
• C. 0.5
• D. 0.6

Answer 1

The correct option is B 0.2

Volume of water = $200m^3$
Area of rectangular field = $1000m^2$
Let ‘h’ be the height of the water level in the field.
Volume of water = Volume of cuboid formed in the field by water.
200 = Area of base × Height = 1000 × h
⇒ h = 0.2 m
So,
Required height = 0.2 m
