5.       Let the edge of the cube be x.


      Volume of the cube = x³
       x³ = 125
      x = 5 inches.

      Number of inches of wire used to form the cube
      = 12x
      = 12 ´ 5
      = 60 inches.

      Ans : A

  6.       Paul's age 5 years ago was x years.
            \ Present age of Paul = (x + 5) years
            From the given information,
              Wilson is one-fourth of Paul's age now.

      = 1 (x + 5) years
       
         4

      Ans : B

   7.      Let the side of the square be x.

     

      Area of square = x²

      Since B is a point on the y- axis. Its x - co-ordinate is 0.

      Co-ordinates of point B º (0,a) where a has to be calculated.

      To find side of a square, we solve x² = 81, i. e. x = ± 9

      Diagonals of a square are equal and they are perpendicular bisectors of each other.

       Let  l(OB) = l(OA) = a
