Answer 1

Lateral surface area of cuboid=2(l+b)h
Length = 50m
Breath = 40m
Height = 10m
So, 2(50+30)10
160*10
1600m
So now we have to add the surface area of celling
= l*b
= 50*40
= 2000m
Then add both surface area = 1600+2000
= 3600 sq. Meter
So cost of white washing is = 3600*20
= 72000₹
The cost of white washing is 72000₹ Answer
