The length, breadth and height of a room are 5 m, 4 m and 3 m respectively. Find the cost of white washing the walls of the room and the ceiling at the rate of Rs. 7.50 m 2 .

Question

Philoid · Accepted Answer

Given,

Dimension of room = 5m×4m×3m

Area of walls = 2(l+b)h = 2×9×3 = 54 m²

Area of ceiling = 20m²

So, total area to be whitewashed = 20+54 = 74m²

Hence, cost of whitewashing at rate Rs 7.50 per m² = 7.50×74 = Rs.555

The length, breadth and height of a room are 5 m, 4 m and 3 m respectively. Find the cost of white washing the walls of the room and the ceiling at the rate of Rs. 7.50 m2.
