Answer :

Given, a room with length, breadth, and height as 8 m, 5 m, and 3 m respectively and the cost of


whitewashing the walls per m2 is Rs. 15.


We know, Area of four walls = 2×(l+b)×h


Area of four walls = 2×(l+b)×h


= 2×(8+5)×3


= 2×13×3


= 78 m2


Cost of white washing the walls at the rate of Rs. 15/m2= 15×78


= Rs. 1170
