A hall is 15 m long and 12 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?

A 720 m3
B 1200 m3
C 900 m3
D 1800 m3

Correct Answer: 1200 m3

Let, the height of the hall (i.e : the wall ) is = x m ATQ, 2(15x + 12x) = 2 (15 × 12) বা, 15x + 12 x = 180 বা, 27 x = 180 বা, x = 18027.'. x  = 203 Volume  = (15×12×203)m3 = 1200m3
