Ex 2.4, 16 What are the possible expressions for the dimensions of the cuboids whose volumes are given below? Volume : 3x2 – 12x First we factorize 3x2 – 12x = 3(x2 – 4x) = 3x(x – 4) Hence, Volume = 3x(x – 4) We know that Volume of cuboid = Length × Breadth × Height Possible dimensions can be Length = 3, Breadth = x Height = x − 4
