WebApr 2, 2024 · The steps to be followed while determining the Cube Root by estimation method are described below. Step 1: The given number is divided into groups of 3 digits starting from the rightmost digit of the number. If any number is left out without forming a group of three, zeros are appended to its left to make it a group of 3 digits. WebJun 9, 2024 · Check if n is a perfect cube, if not then it cannot be a Dudeney number. If n is a perfect cube then calculate the sum of its digits. If the sum of it’s digits is equal to its cube root then it is a Dudeney number else it is not. Below is the implementation of the above approach: C++. Java. WebThus, the cube number of 17 is 4913. It can be written as 17 3 = 4913 or 17 × 17 × 17 = 4913. Example 2: Which of the following are cube numbers? a) 512. b) 2197. c) 125. Solution: a) 512 is a cube number of 8. b) 2197 is a cube number of number 13. c) 125 is a cube number of 5. population density of fiji
