The length, width A. 27 cm²

B. 32 cm²

C. 64 cm²

D. 88 cm²

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 =
