l = 5, b = 4, h = 3
Total surface area of four walls = 2 (l + b) h
= 2(5 + 4) 3
= 54 m^2
Cost of white washing 1 m square area = 12 rs
Cost of white washing 54 m square area = 12x54 = 648 r
Total surface area of four walls = 2 (l + b) h
= 2(5 + 4) 3
= 54 m^2
Cost of white washing 1 m square area = 12 rs
Cost of white washing 54 m square area = 12x54 = 648 r
