Question :
What are the possible expressions for the dimensions of the cuboid whose volume is 12ky² + 8ky - 20k ?
Solution :
Given volume = 12 ky²+7ky -20 k
To Find : It's Dimensions
Factorising it :
12 ky²+7ky -20 k
= 4k(3y²+2y-5)
= 4k[y(3y+5)-1(3y+5)]
= 4k[(3y+5)(y-1)]
Length = 4k
Breadth = 3y+5
Height = y-1
