      Question

      Total surface area of a Cuboid is 592 cm ² and the

      Sum of its Length, breadth and height is 30cm, then find out the sum of the squares of its length, breadth and height?
      A 310cm² Correct Answer Incorrect Answer
      B 210cm² Correct Answer Incorrect Answer
      C 208cm² Correct Answer Incorrect Answer
      D 308cm² Correct Answer Incorrect Answer

      Solution

      Sum of Length, Breadth and height of a cuboid is 30 cm (l+b+h) = 30cm Total surface area of cuboid = 592cm² 2(lb+bh+hl) = 592cm² Sum of Square of Length, Breadth and Height = l² +b² +h² l² +b² +h² = (l+b+h)² - 2(lb+bh+hl) l² +b² +h² = (30)² - 592 = 900 – 592 = 308
