Answer:
LET THE LENGTH, BREADTH AND HEIGHT OF RECTANGULAR BOX BE 2x ,3x AND 4x.
REQUIRED SHEET TO COVER THE BOX
= TOTAL SURFACE AREA OF BOX
= 2(lb+bh+hl)
= 2 (2x*3x+3x*4x+4x*2x)
= 2(6x^2+12x^2+8x^2)
= 2(26x^2)
= 52x^2
SORRY , BUT YOU HAVE TO GIVE TWO COSTS BUT ONLY ONE IS PROVIDED,SO JUST CORRECT THE QUESTION AND PLEASE ALSO PUT THE CORRECTION IN COMMENT SECTION IF YOU WANT THE QUESTION TO BE SOLVED FURTHER.
