A rectangular sheet of wood has four small squares removed from the corners. It is then cut to make a box that is 5 cm by 4 cm with a volume of 60 cm 3 . (Four pieces of size A4 are removed.) Find the original area of the sheet of wood.

Dear Sathyaram,

 l x h x w = 60 
     h(5)(4) = 60
     h = 3

     A(1) = 4 x 5 = 20
     2A(2) = 2(3)(5) = 30
     2A(3) = 2(3)(4) = 24
     4A(4) = 4(3)(3) = 36

     Total A = A(1) + 2A(2) + 2A(3) + 4A(4)
             = 20 + 30 + 24 + 36
             = 110cm2

Best Of Luck...!!!!
