Step-by-step explanation:
Given
- Length of room. = 7m
- Breadth of room. = 5m
- Height of room. = 3m
We are told to whitewash Wall and celling
therefore surface area =
TSA of room - Area of floor
= 2( lb + bh + lh) - lb
= 2 ( 35 + 15 + 21 ) - 35
= 2 ( 71 ) - 35
= 142 - 35
= 107 m²
Now the cost is given as Rs 11 / m²
Therefore cost of whitewashing is 11 × 107
= 1177 Rs
