Answer:
Given length of swimming pool =20m
Breadth of swimming pool =15m
Height of swimming pool =4m
Curved surface area of cuboid =2(l+b)h
=2[20+15]×4
=2×35×4
CSA of cuboid (pool)=280m2
If cost of painting is =20 Rs/sq. m
then cost of painting four walls of pool =20×280
Cost =5600Rs.
Hence cost of painting four walls of swimming pool is Rs. 5600.
