suppose each side of its base has length x cm show that the total surface area of the box is given by a=6x^2+4x
Solution
If the base has length \'x\' ,
the area of one side of the square = x2
there are 6 sides and the total area = 6x2 and not 6x2 +4x
the information about the box must be given . (square base or triangular base)
