Total surface area of a rectangular box
=2(lw+wh+hl)
where l,w,h=length, width and height respectively.
Total surface area of a cubical box (all sides equal to "a"
=6a²
Total surface area of a Rectangular prism : see above for rectangular box
=2(lw+wh+hl)
where l,w,h=length, width and height respectively.
