There is problem in q I think you should also give the ratio of length, breadth and height. ( upvote if agree )

For x=5, Volume is: 5^3 + 2(5^2) - 5 - 2 = 125 + 50 - 5 - 2 = 168

As, volume of cuboid = l x b x h, therefore, dimensions = 4 x 6 x 7.

X=5

x3 2x2-x-2

= 5^3 2*5^2-5-2

=125 50-7

=118 50

=168

option a ) 4*6*7=168 therefore a is answer

x3 2x2-x-2

= 5^3 2*5^2-5-2

=125 50-7

=118 50

=168
