Volume of the air in the room = length X width X height = 28 X 16 X height = 2240 So, height of the room = 2240 ÷ (28 X 16) = 5 metres So, area of large side of the wall = length X height = 28 X 5 = 140 m2 Area of small side of the wall = 16 X 5 = 80 m2 So, total area of the wall = (140 X 2) + (80 X 2) = 440 m2 So, cost of painting the side walls of the room = 440 X 32 = Rs. 14,080
