Question

the length,breadth and height of a room are 6m,4m and 3m respectively.Gind the cody of white washing the walls of the room and ceiling at the rate of Rs 20 per m²​

Answer 1

Answer:

1680₹

Step-by-step explanation:

See we whitewash the walls and the ceiling only and not the floor.

So the total surface area(including floor0) = 2{lb+bh+hl}

and Total surface area to white washed = 2{lb+bh+hl} - {lxb} (this is the area of the floor as its generally taken)

-> 2{24+12+18} - {24} = 84 m sq

Cost of white washing 1 m sq = 20₹

Cost of white washing 84 m sq = 20x84 = 1680 ₹
