Because numbers can have no rules, to calculate the sum, first calculate the cubic value of each number, and then add their cubic values.

Of course, if the numbers are regular, such as calculating the sum of two cubes, sum and difference of two cubes calculator is recommended; or calculating the sum of cubes of first n numbers, sum of cubes of first n natural, odd or even numbers calculator is recommended; or calculating the sum of cubes of consecutive numbers in a range, sum of consecutive cubes calculator is recommended.

## Solved Examples Using Sum of Cubes Calculator

### Example 1: What is the sum of cubes of 10, 15 and 20.5?

Direct calculation

10

^{3}+ 15^{3}+ 20.5^{3}= 1000 + 3375 + 8615.125

= 12990.125

Use the sum of cubes calculator to calculate the sum of cubes of 10, 15 and 20.5.

The calculated result is consistent with the above.

### Example 2: Find the sum of cubes of 5, -8, 9 and -12?

Direct calculation

5

^{3}+ (-8)^{3}+ 9^{3}+ (-12)^{3}= 125 + (-512) + 729 + (-1728)

= 125 – 512 + 729 – 1728

= -1386

Use the sum of cubes calculator to find the sum of cubes of 5, -8, 9 and -12.

The answer is also -1386.
