Question

10 cubic metres clay in uniformly spread on a land of area 10 acres. The rise in the level of the ground is

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

Answer 1

The correct option is A

1 cm

$\text{Volume of clay}=10m^3$

$\text{Area of land}=10acres$$=10\times 100=1000m^2$

$\therefore \text{Rise of level by spreading the clay}$$=\frac{Volume}{Area}=\frac{10}{1000}=\frac{1}{100}m=1cm$
