The inverse operation of cubing 998 is extracting the cube root of 998, explained here.

In the next section we elaborate on the cube 998.

What is 998 Cubed?

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

Hence, a cube with side length 998 has an area of 994,011,992.

The sum and the differences of two cubes, for example with side length 998 and 997, can be calculated with the following formulas:

  1. a3 + b3 = (a + b) × (a2 – ab + b2) ⇔ a3 = (a + b) × (a2 – ab + b2) – b3
    With a = 998, b = 997 and the equivalence we get:
    (998)3 = 1995 x (9982 – 998 × 997 + 9972) – 9973 = 1995 x (996004 – 995006 + 994009) – 991026973 = 1995 x 995007 – 991026973 = 994,011,992
  2. a3 – b3 = (a – b) × (a2 + ab + b2) ⇔ a3 = (a – b) × (a2 + ab + b2) + b3
    With a = 998, b = 997 and the equivalence we get:
    (998)3 = (9982 + 998 × 997 + 9972) + 9973 = 996004 + 995006 + 994009 + 991026973 = 994,011,992

As follows from (1), 998 cubed can be calculated from 997 cubed and 998 squared using the identity:

n3 = (2 × n – 1) × (n2 -n + 1) – (n-1)3
(998)3 = (2 × 998 – 1) × (9982 – 998 + 1) – (997)3 = 1995 × (996004 – 997) – 991026973 = 1995 × 995007 – 991026973 = 994,011,992

Using the second formula 998 cubed can be also be computed with this identity:

n3 = (n-1)3 + 3n2 -3n + 1
(998)3 = 9973 + 3 × 9982 – 3 × 998 + 1 = 991026973 + 3 × 996004 – 3 × 998 + 1 = 991026973 + 2988012 – 2994 + 1 = 994,011,992
