Question

If $10$ cubic metres of clay is uniformly spread on a land of area $10$ acres, what is the rise in the level of the ground?

• A. $1cm$
• B. $10cm$
• C. $100cm$
• D. $1000cm$

Answer 1

The correct option is A $1cm$

Rise in level = $\frac{volumeofclay}{Areaofland}=\frac{10m^3}{10acres}$

Now, $1$ ares $=100$$m^2$

$\therefore$ Rise in land = $\frac{10}{1000}=0.01m=1cm$
