Question

The walls and ceiling of a room are to be plastered. The length, breadth and height of the room are 4.5 m, 3m and 350 cm respectively. Find the cost of plastering at the rate of rupees 8 per metre square​

Answer 1

Convert metres into centimeters

Ceiling = 450×300=135000cmsq

4 walls of room = 450×350×2 + 300×350×2 =525000

Therefore total surface area for plastering = 135000+525000=660000

Now convert 660000cmsq into msq

So 660000cmsq = 6600ms

Cost = 6600×8 = 52800₹
