649 Cubed

649 cubed, (649)3, is the number you get when multiplying 649 times 649 times 649.

It can also be looked at as exponentiation involving the base 649 and the exponent 3.

The term is usually pronounced 3rd power of six hundred forty-nine or six hundred forty-nine cubed.

The cube of 649 is a perfect cube because the number is the product of the three equal integers 649.

It can be written as 649 × 649 × 649 or in exponential form.

The inverse operation of cubing 649 is extracting the cube root of 649, explained here.

In the next section we elaborate on the cube 649.

What is 649 Cubed?

A cube is a three-dimensional shape with 6 equal square faces.

Hence, a cube with side length 649 has an area of 273,359,449.

The sum and the differences of two cubes, for example with side length 649 and 648, can be calculated with the following formulas:

  1. a3 + b3 = (a + b) × (a2 – ab + b2) ⇔ a3 = (a + b) × (a2 – ab + b2) – b3
    With a = 649, b = 648 and the equivalence we get:
    (649)3 = 1297 x (6492 – 649 × 648 + 6482) – 6483 = 1297 x (421201 – 420552 + 419904) – 272097792 = 1297 x 420553 – 272097792 = 273,359,449
  2. a3 – b3 = (a – b) × (a2 + ab + b2) ⇔ a3 = (a – b) × (a2 + ab + b2) + b3
    With a = 649, b = 648 and the equivalence we get:
    (649)3 = (6492 + 649 × 648 + 6482) + 6483 = 421201 + 420552 + 419904 + 272097792 = 273,359,449

As follows from (1), 649 cubed can be calculated from 648 cubed and 649 squared using the identity:

n3 = (2 × n – 1) × (n2 -n + 1) – (n-1)3
(649)3 = (2 × 649 – 1) × (6492 – 649 + 1) – (648)3 = 1297 × (421201 – 648) – 272097792 = 1297 × 420553 – 272097792 = 273,359,449

Using the second formula 649 cubed can be also be computed with this identity:

n3 = (n-1)3 + 3n2 -3n + 1
(649)3 = 6483 + 3 × 6492 – 3 × 649 + 1 = 272097792 + 3 × 421201 – 3 × 649 + 1 = 272097792 + 1263603 – 1947 + 1 = 273,359,449
