Step-by-step explanation:
If the length, breadth and height are in the ratio 3:2:1 then the dimensions are 3x, 2x and x for some value of x. Therefore, in terms of x, the volume = .
So
x = 4
The dimensions of the box are
i.e. 12, 8 and 4 cm.
Therefore its surface area =
= 2(96 + 48 + 32)
= 352

384 = 3x × 2x × 1x
384 = 6x³
384/6 = x³
64 = x³
x = 4
l = 12cm , b = 8cm, h 4cm
TSA = 2(lb + bh + hl)
TSA = 2(96 + 32 + 48)
TSA = 2(176)
TSA = 352cm²
