1.	A room is 5m long,4m wide and 3m high.Find its total surface area(floor,ceiling and walls)
Answer» ANSWER: =2×3 (5+4) =54m^2 . AREA of ceiling = (l×b) =20m^2 , Area of floor is equal to ceiling area as ROOM is of cuboidal shape , so area is 20m^2. Area of 4 walls +area of ceiling =(54+20) m^2 =74m^2. hope it helps you
