Question

16. What are the possible expressions for the dimensions of the cuboids whose volumes
are given below?
(ii) Volume: 12ky2 + 8ky - 20k​

Answer 1

12ky2 + 8ky - 20k

= 4 (3ky2 + 2ky - 5k)

= 4k (2y2 + 2y -5)

= 4k (3y + 5) (y-1)

Hence the possible expression for length = 4k

Hence the possible expression for breadth= (3y+5)

Hence the possible expression for height=(y-1)
