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 =
