surface area of cube is 6a square
it can be expanded as 2[x square+x square+x square] i just compared the equation with the surface area of cuboid
let the side of the cube x
then,
       length=breadth=x
       edge becomes x/2+x=3x/2
change in surface area=2[x square+xX3x/2+xX3x/2]
                                     on doing LCM
                                    the final answer 8 x square

kutty1708: f u find it wrong just text me back i will re send u the answer
