Question

A swimming pool is 50 m in length , 30 m in breadth and 2 m in depth . Find the cost of cementing its floor and walls at the rate of Rs 30 per square metre .​

Answer 1

Answer:

you need to find the Lateral surface area+area of top

Then multiply it with 30

Explanation: Total area to cement= 2(lh+bh)+ lb

Hence, area to be cemented is 2(100+60) + 50*30

So, area to be cemented is 1820 m

Cost= area *30

=1820 * 30

=₹54,600
