Understanding the Cube Dimensions
The original cube has a side length of 10 cm. It is painted with a 2 cm wide red strip along all edges of each face.
Calculating the Inner Dimension
- The red strip removes 2 cm from each side of the cube.
- Since the strip is painted on all sides, we need to subtract 4 cm (2 cm from each side) from the original dimension.
- Thus, the dimension of the unpainted inner cube is:
- 10 cm - 4 cm = 6 cm.
Volume of the Smaller Cubes
- The cube is divided into 125 smaller cubes.
- Since 125 is equal to 5^3, each smaller cube has a side length of:
- 10 cm / 5 = 2 cm.
Determining the Number of Unpainted Cubes
- The unpainted inner cube has dimensions of 6 cm, and since each smaller cube has a side of 2 cm, we can determine how many smaller cubes fit within the unpainted area:
- Number of smaller cubes along each dimension = 6 cm / 2 cm = 3 cubes.
- Therefore, the total number of smaller cubes that are completely unpainted is:
- 3 x 3 x 3 = 27.
Conclusion
The total number of smaller cubes without any color is 27. Thus, the correct answer is option C.

The cubes having only one face painted are the cubes which lie at the centre of each face of big cube. There are 6 faces of a cube. So, required no. of cubes having one face painted = 6
Cubes of same size are arranged in the form of cube on a table then a column of five cubes is removed from each of the four cubes is removed from each of the four corners. All the exposed faces of rest of the cube are coloured yellow. Then how many small cubes are there in the solid after the removal of the column?- a)100

From positions A and B we conclude that 1, 5, 6 and 3 lie adjacent to 4. Therefore, 2 must lie opposite 4. From positions A and B we conclude that 4, 3, 2 and 5 lie adjacent to 6. Therefore, 1 must lie opposite 6. Thus, 2 lies opposite 4, 1 lies opposite 6 and consequently 5 lies opposite 3.
2 lies at the bottom face in position B.

From figures (i), (ii) and (iii), we conclude that 3, 4, 6 and 1 dots appear adjacent to 2 dots. Therefore, 5 dots appear opposite 2 dots. Now, from figures (i) and (iii), we conclude that 2, 4 and 1 dots appear adjacent to 3 dots. Therefore, either 5 or 6 dots appear opposite 3 dots. Since, 5 dots appear opposite 2 dots, it follows that 6 dots appear opposite 3 dots.
