  1.       Let the edge of the cube be x.


  2.       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
