A room is 30 m long and 24 m broad. If the sum of the areas of the floor and the ceiling is equal to the sum of the areas of four walls, the volume of the hall is:
Answers:	A) 9.6 m3	B) 96 m3	C) 960 m3	D) 9600 m3	E) 96000 m3
Let the height be H   2(30+24) x H – 2(30-24)   H=(2(30x24))/(2(30+24)) = (30x24)/54 = 40/3 m   Volume = 30x24x40/3 = 9600 m3   answer :9600 m3
