Madhya Pradesh Police Exam Model Paper 3

Let the no. of cubes of side a that can be made by melting the given cuboid = n
Total volume of these cubes $=\mathit{n}{\mathit{a}}^3$
Total volume of all the smaller cubes is equal to the volume of the original cube
As a = 2
$\Rightarrow 8\mathit{c}\mathit{m}\times 4\mathit{c}\mathit{m}\times 27\mathit{c}\mathit{m}=23\times \mathit{n}$
$\Rightarrow \mathit{n}=108$
