Cube of a number:
In mathematics, a cube number is a number that has been multiplied by itself three times. It can also be called a number cubed. This number is represented by the symbol ³. Perfect cubes are numbers that are the cubes of integers. 125, for example, is a perfect cube since it is composed of 5 × 5 × 5 = 53. The cube of a number is found by multiplying the number by itself, then multiplying the obtained product by the original number again.
For Example: Using the same method, find the cube of 6. It is known that the cube of N is N × N × N. As a consequence, the cube of 6 is 6 × 6× 6. We first have to determine the value of 6 * 6 in order to find the cube of 6. The value of this is 36. We will now calculate 36 × 6. The result is 216. This means that the cube of the number 6 is 216.
Cube Root of a number:
Root refers to the primary source or origin. Hence, we simply need to consider “what number should be taken as the cube of the given number.” Mathematically, cube roots can be defined as the number that must be multiplied three times to get the original number. In the case of y being the cube root of x, the cube root formula can be seen. ∛x = y. The radical symbol ∛ can be used as a cube root symbol for any number, and it includes a small number 3 at the top left of the symbol. Similarly, one can also use a number’s exponent 1/3 as a notation for cube root. As with the square root symbol, the cube root symbol operates similarly. It is often termed a radical, and the number or expression above the top line is known as the radical. As a grouping symbol, the cube root symbol condenses all operations in the radicand as if they were in parentheses. A square root can have only one value; it can never be zero. However, a cube root can have any value: positive, negative, or zero. Another aspect of a cube root that differs from a square root is the domain restriction on its radicand: a negative radicand can still provide a valid result.

Cube root formula: where y is the cube root of x. ∛x = y. Cube roots are obtained by multiplying a number by itself three times in order to obtain the original number. For example, the cube root of 5. The number 5 is prime. It only has two factors, 5 and 1, since it is a prime number. In other words, 5 cannot be factored into a product of 5 whole numbers. As a result, the cube root of 5 is a fraction or decimal value. Therefore, the cube root of 5 = ∛5 = 1.71.
Conclusion:
Solving cubic equations usually involves using the cube root. In everyday mathematics, like powers and exponents, cube roots are employed. In addition to finding the sides of triangular cubes when the volume of the cube is given, they may also be used for many other functions. It is especially useful for solving the dimensions of a three-dimensional object with a given volume.
