Sum of Cubes Calculator

Welcome to the sum of cubes calculator, this calculator is used to calculate the sum of cubes of numbers. These numbers can be irregular. You can enter multiple numbers at a time, which can be integers, negative numbers, or decimals. The numbers are separated by commas or newlines.

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.

Direct calculation

10³ + 15³ + 20.5³

= 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.

Direct calculation

5³ + (-8)³ + 9³ + (-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.
