What are the possible expressions for the dimensions of the cuboids whose volumes are given below?
 
(i) Volume : \(3x^2 – 12x\)
 
Length, breadth and height \(=\)
 
(ii) Volume: \(12ky^2 + 8ky – 20k\) 
 
Length, breadth and height \(=\)
Answer variants:
\(4k, (3y + 5)\) and \((y – 1)\)
\(3, x\) and \((x – 4)\)
\(3x, 2x\) and \((2-x)\)
\(4y, (3k + 5)\) and \((k – 1)\)
