A cube root 5 of a number is a number that when multiplied by itself three times yields the original number. Furthermore, we denote a cube root using the symbol \(\sqrt [ 3 ] { }\), where \(3\) is called the index 6 .
The cube root won't be an exact number, if that's what you're asking. To get an idea of what it might be, 4 is found in between 1 and 8 This means that the cube root of 4 will be in between cube root of 1 and cube root of 8, or in other words, between 1 and 2.

Since 3 is not a perfect cube, therefore it is a little difficult to find its cube root. But, for perfect cubes like 8, 27, etc., the cube root of such numbers are whole numbers, because, 2 3 = 2×2×2 = 8 and 3 3 = 3×3×3 = 27. Hence, cube root of 8 is 2 and of 27 is 3. Cube root of any number n is a number x, such as x 3 = n.
For example, a cube has volume ‘x’ cubic meter, then we can find the side-length of the cube by evaluating the cube root of its volume, i.e., side = 3 √x. Let us see the values of cubic roots.

The cube root of a number is a special value that, when used in a multiplication three times, gives that number. Example: The cube root of 27 is 3 because 3 × 3 × 3 = 27. Also the cube root of 64 is 4 because 4 × 4 × 4 = 64, and so on. See: Square Root. Cubes and Cube Roots.
When you cube a number, you raise it to an exponent of 3. For example: 2^3 = 2*2*2 = 8. A cube root reverses this process. You are being asked to find the number that was originally "cubed". For example: cube root (8) = 2 because 2^3 = 8. Hope this helps. 1 comment.
The cube root formula is used to give the cube root value of any number. To recall, the cube of any number is found by multiplying the number three times. For example, 5 × 5 × 5 = 125. Now, the cube root formula is the vice versa of the cube formula. Formula for Cube Root. Check the example below for detail: 5 Cube = 5 3 = 125
