Question

There is a playground measuring $50 m \times 30 m$. In one corner of the ground, a pit dimensions $5 m \times 4 m \times$ $1 m$ is dug and the mud is spread all over the ground uniformly. What is the approximate height of the layer of mud spread?

• A. $7 mm$
• B. $8 mm$
• C. $14 mm$
• D. $10 mm$

Answer 1

Answer: (C)

(i) Rise in height $=$
Volume of pit
$\overline{\text { Area of ground on which mud is spread }}$
(ii) Find the area of playground and the volume of pit.
(iii) Rise in the level =
Area of playground - Area of pit
Volume of pit
