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. Choose the correct choice from the following answers.
A) 120 m ³  B) 400 m ³  C) 660 m ³  D) 720 cm m ³  E) none

Rationale: 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 cm ³ answer d
Answer: D
