Therefore the surface area to be painted of a room

 = {2(l×h+b×h) + l×b} square units

Step-by-step explanation:

Let, length of the room = l

breadth of the room = b

height of the room = h

Total surface area of all the wall of the room = 2(l×h+b×h) square units

The surface  area of the roof is = l×b square units

Therefore the surface area to be painted of a room

 = {2(l×h+b×h) + l×b} square units
