Answer:
volume = l×b×h
=(x²-2) (2x+2) ( x-1)
=2x³+x³-4x-4+2x²-x²-2x+2
=4x³+x²-6x-2
=2x²(2x+1)- 3(2x+1)
=(2x²-3)(2x+1)

vole of cuboid is equal to l ×b ×h
=( x*2 -2 )(2x*2 - 2x +2x -2 )
= (x*2 -2 )(2x*2 - 2 )
= ( 2 x*4 -2x*2 -4x*2 +4 )
= ( 2x*4 -6x*2 +4 )
this is your answer i hope this helpful for you
