Answer 2

The required number has 8 in its unit digit's place.

Step-by-step explanation:

• We must know what are the unit digits of the numbers having 0, 1, 2, ..., 9 in the unit digit place of their cube roots.

• 1. When the cube root has 0 in the units place, the number ends with 0.

• 2. When the cube root has 1 in the units place, the number ends with 1.

• 3. When the cube root has 2 in the units place, the number ends with 8.

• 4. When the cube root has 3 in the units place, the number ends with 7.

• 5. When the cube root has 4 in the units place, the number ends with 4.

• 6. When the cube root has 5 in the units place, the number ends with 5.

• 7. When the cube root has 6 in the units place, the number ends with 6.

• 8. When the cube root has 7 in the units place, the number ends with 3.

• 9. When the cube root has 8 in the units place, the number ends with 2.

• 10. When the cube root has 9 in the units place, the number ends with 9.

• So, we conclude that our required number has 8 in its units place.
