The length, width and height of a rectangular solid are in the ratio of 3 : 2 : 1. If the volume of the box is 48 cm3, the total surface area of the box is


Given,


Ratio of length , width and height of rectangular solid = 3:2:1


Volume of box = 48 cm3


Let length of box = 3x cm


Breadth of box = 2x cm


Height of box = x cm


Volume of box = v =


= 6x3 = 48


=


=


Hence . length = 3x = 3×2 = 6 cm


= bredth = 2x = 2×2 = 4 cm


= height = x = 2 cm


Total surface area of box =
