Question

On a particular day, the rainfall recorded in a terrace 6 m long and 5 m broad is 15 cm. The quantity of water collected in the terrace is

• A. 300 litres
• B. 450 litres
• C. 3000 litres
• D. 4500 litres

Answer 1

The correct option is D

4500 litres

$\text{Dimension of the terrace}=6m\times 5m$

$\text{Height of water on it}=15cm$

$\therefore \text{Volume of water collected on it}$

$=\frac{6\times 5\times 15}{100}{m}^3=\frac{9}{2}{m}^3$

$\text{In litres, water's quantity}=\frac{9}{2}\times 1000l$

$=4500l$
