Answer:
Length = 2
Breadth = k
Height = x² + 4k -10
Step-by-step explanation:
Here Volume = 2kx² + 8kx - 20k
= 2k( x² + 4x - 10) ------- ( i )
Also Volume = Length × Breadth × Height ------- ( ii )
On comparing ( i ) and ( ii )
We can say
Length × Breadth × Height = 2 × k × (x² + 4k - 10)
Dimensions of Cuboid = 2 × k × (x² + 4k - 10)
Where Length = 2
Breadth = k
Height = x² + 4k -10

but the answer is different.
it is an expression, so answer can be different. You may factorise the expression of height further
also check your question, is it 2kx^2 or 12kx^2 ?
oops sorry.it is 12kx^2
can you send me the actual answer? please..
not being able to edit the answer will be 4k , (3x + 5) and ( x - 1)
