Answer» Correct Answer - Option 1 : 4

Total cubes = 125

The only cubes present at the upper face and four corners of cube that will be visible to three sides of cube.

A cube is formed by 11 cube horizontally and 11 cube vertically and remaining 4 cube will be visible.

number of cubes required to make largest possible cube = 11 × 11 = 121

∴ Remaining cube = 125 - 121 = 4
