If the areas of three adjacent faces of a cuboidal box are 729 cm2, 529 cm2 and 289 cm2 , respectively, then find the volume of the box. |
10557 cm3 10560 cm3 10555 cm3 10551 cm3 |
10557 cm3 |
We know that, Area of single cuboidal face = l × b, Volume of Cuboid = l × b × h We have, Areas of 3 adjacent faces = 729 cm2, 529 cm2, and 289 cm2 According to the question, l × b = 729 b × h = 529 h × l = 289 l × b × b × h × h × l = 729 × 529 × 289 l2 × b2 × h2 = 729 × 529 × 289 l × b × h = \(\sqrt {729×529×289}\) = l × b × h = 10557 |
