# Fill in the blanks to make the correct statement.

A cube of 5cm is cut into 1cm cubes. The percentage increase in volume after such cutting is _______.

Answer :

Given,

A Cube of side 5cm is cut into 1cm cubes.

Volume of a cube = 5 × 5 × 5 = 125cm^{3}

Now, the big cube is cut into 1cm cubes.

The number of small cubes =

Thus, the volume of big cube = the volume of 125 cubes having an edge 1cm

Hence, there is no change in the volume.
