Answer 2

Let length = 3x
Breadth= 2x
And height = x
Formula for t.s.a = 2( lb+bh+hl)
550 unit = 2(3x*2x + 2x*x + x*3x)
550/2 unit = (6x^2+ 2x^2+ 3x^2)
275 unit = 11x square
275/11 = x square
√25 = x
5 = x
Now length = 3x = 3*5 = 15 unit
Breadth = 2x = 2*5 = 10 unit
Height = x = 5 unit

Now volume of cuboid
=l*b*h
= 15*10*5
= 750 unit ^3

* i have mention unit because u have not specified the value as in cm or m etc.

Hope it helps
