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.
