Question

The rainfall recorded on a certain day was $8$ cm. Find the volume of water that fell on a $20$ hectare field.

• A. $16\times {10}^{3}l$
• B. $16\times {10}^{4}l$
• C. $16\times {10}^{5}l$
• D. $16\times {10}^{6}l$

Answer 1

Answer: (D)

$16\times {10}^{6}l$

The volume of water $=$ Area of ground $\times h$
$=20$ hectares $\times 8$

$=20\times 10000\times \frac{8}{100}$

$=16000m^3$

$=16\times {10}^{6}l[\because 1m^3=1000l]$
