numbers go from right to left

Translation

One, eight, twenty-seven, sixty-four, one hundred and twenty-five, two hundred and sixteen, three hundred and forty-three, five hundred and twelve, seven hundred and twenty-nine are the cubes of the numbers from one to nine.[1] The product of three (equal numbers) is the cube (of that number).

Verse

घनेऽथ तन्मूलवर्गतदादि त्रिवधे ततः ।

आदिवर्गान्त्यत्रिवधे युतेष्वङ्केष्वथो घनः ॥ १६ ॥

Translation

To the cube (of the last digit) add (on the right) the product of thrice the square of the last digit and the remaining digits. Then add (on the next place to the right) the product of thrice the last digit and the square of the remaining part and then add the cube of the remaining part (on the next place to the right). This is (repeated until all the digits are finished to get) the cube.

Example: Cube of 35

Here the number considered is 35 , 3 is the last digit and the remaining digit is 5. Apply the method of cubing.

Cube of the last digit (33) = 27 2 7
Thrice the square of the last digit (3) multiplied by the remaining digit (5)

3 X 32 X 5 = 135. To be placed in the next place such that 5 is one place next to 7

1 3 5
Thrice the square of the remaining digit (5) multiplied by the last digit (3)

3 X 52 X 3 = 225. To be placed in the next place such that 5 is one place next to 5

2 2 5
Cube of the remaining digit (53) = 125. To be placed in the next place such that 5 is one place next to 5 1 2 5

Cube of 35 = 42875

Example: Cube of 123

Here the number considered is 12 , 1 is the last digit and the remaining digit is 2. Apply the method of cubing.

Cube of the last digit (13) = 1 1
Thrice the square of the last digit(1) multiplied by the remaining digit (2)

3 X 12 X 2 = 6. To be placed in the next place
