If the areas of the three adjacent faces of a cuboidal box are 120 cm², 72 cm² and 60 cm² respectively, then find the volume of the box.	Pick.
A) 120 m³	B) 400 m³	C) 660 m³	D) 720 cm m³	E) None
Sol.   Let the length, breadth and height of the box be, l, b, and h respectively, Then,   Volume = lbh = √(lbh)² = √lb * bh * lh = √120 * 72 * 60 = 720 cm³   Answer 720 cm m³
