The one digit in the cube root of the cube number 1728 is 2.
The unit digit of 1728 is 8. With the help of the cube table given above, check the cube of which number has 8 at its unit place. So, we can say that the unit digit of the cube root of 1728 is 2.
1728=12×12×12. Thus, the cube root of 1728 is 12.
Cube root of 1728, 3√1728 = 12
Since 1728 is a four-digit number, so finding its prime factors can be a little lengthy. Thus, we can use an estimation method for fast calculation. For this method, we have to learn the value of cubes of natural numbers from 1 to 10, which is provided here in the later part.
Since 1000000 is a perfect cube, the cube root of 1000000 is exactly 100.
1728 is a perfect cube because its cube root is 12.
This corresponds to the last digit of the 100th number in this sequence, which is 199. The digits of 199 are 1, 9, and 9. The last digit (the 3rd digit) is 9. Therefore, the 489th digit in the sequence 123456789101112... is 9.
A cube number is the product of three identical factors (e.g. 2 x 2 x 2 = 8). So, a cube number is any number which has been multiplied by itself, twice. Sometimes, the language 'cubed' is used (e.g. '2 cubed' = 2 x 2 x 2 = 8).
As a cubic perfect power, it is also a highly powerful number that has a record value (18) between the product of the exponents (3 and 6) in its prime factorization. 1728 has twenty-eight divisors, which is a perfect count (as with 12, with six divisors).
As 2197 is a perfect cube, it will be very easy to calculate the cube root of 2197. Therefore, = (13 * 13 * 13) = 13. Hence, the cube root of 2197 is 13. Hence, the cube root is the inverse method of determining the cube of a number.
The value of the cube root of 1728 is 12.
Prime factorization is now used to translate the given integer into a product of prime factors. The number 999 is not a perfect cube since 37 is left behind after grouping (making triples). The given number in option 2 is 1000. The given number 1000 makes triplets in prime factorization and hence it is a perfect cube.
All these four numbers, 216, 512 and 729 break in three same factors. These three has perfect cube, But 666 cannot be written in same three factors. ⇒ 666 is not a perfect cube.

The largest 4-digit number is given in the option = 9999, which is not a perfect cube. Third largest = 8000 = 203. The largest four-digit number which is a perfect cube is 9261.
The cube root of 8000 is the number which when multiplied by itself three times gives the product as 8000. Since 8000 can be expressed as 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × 5. Therefore, the cube root of 8000 = ∛(2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × 5) = 20.
Cube root of number is a value which when multiplied by itself thrice or three times produces the original value. For example, the cube root of 27, denoted as 3√27, is 3, because when we multiply 3 by itself three times we get 3 x 3 x 3 = 27 = 33.
Cube root of a number can be found by a very simple method which is the prime factorization method. Cube root is denoted by '∛ ' symbol. Example: ∛8 = ∛(2 × 2 × 2) = 2. Since, 8 is a perfect cube number, it is easy to find the cube root of a number.
