# What will be the height of column? If

If a cubic metre of a solid be cut into 25 cm cubes, and these cubes be piled up in a column, then the height of the column will be

- 8 metres
- 16 metres
- 32 metres
- 4 metres

**Answer: (2) 16 meters**

**Explanation:-**The side of cube = 1 m

Then, the volume of the cube = 100 x 100 x 100 cm cube

The number of cube of 25 cm cut from the 1 meter solid cube = 100 x 100 x 100/25 x 25 x 25

= 4 x 4 x 4

= 64

Then, the height of the column = 64/4

= 16 meters.

Hence,the answer is (2) 16 meters.
