Question
The length, breadth and height of a room are 8m, 10m and
12m respectively. Find the cost of white washing the room at the rate of Rs 15 per m²?Solution
Area of walls = 2h (l + b) Length = 8m, breadth = 10m and height = 12m So, area of 4 walls = 2 × 12 (8 + 10) = 24 × 18 = 432 m² Area of ceiling = l × b = 8 × 10 = 80 m² So total area for white wash = 432 + 80 = 512 m² Rate per square meter = Rs 15 Then, Total cost = 512 × 15 = Rs. 7,680
