Question 8 Mensuration Exercise 17.1

How many cubic metres of soil must be dug out to make a well 20 metres deep and 2 metres in diameter?



The capacity of a cylinder is measured by its volume, which determines how much material it can carry.

Given diameter of the well, d = 2 m

Radius, r = d/2 = 2/2 = 1 m

Depth of the well, h = 20 m

Volume of the well, V =π r2h

= (22/7)×12×20

= 62.85 m3

Hence the amount of soil dug out to make the well is 62.85 m3. M L Aggarwal - Understanding ICSE Mathematics - Class 10 chapter Mensuration Question 8 Solution image
