# 998 Cubed

998 cubed, 9983, is the number you get when multiplying 998 times 998 times 998. It can also be looked at as exponentiation involving the base 998 and the exponent 3. The term is usually pronounced 3rd power of nine hundred and ninety-eight or nine hundred and ninety-eight cubed. The cube of 998 is a perfect cube because the number is the product of the three equal integers 998. It can be written as 998 x 998 x 998 or in exponential form. Read on to learn everything about the number nine hundred and ninety-eight cubed, including useful identities.

9983 = 994011992
998 x 998 x 998 = 994011992

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, and there you can also find our calculator.

## 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 994011992.

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:
9983 = 1995 x (9982 – 998 × 997 + 9972) – 9973 = 1995 x (996004 – 995006 + 994009) – 991026973 = 1995 x 995007 – 991026973 = 994011992
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:
9983 = (9982 + 998 × 997 + 9972) + 9973 = 996004 + 995006 + 994009 + 991026973 = 994011992

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
9983 = (2 × 998 – 1) × (9982 – 998 + 1) – (997)3 = 1995 × (996004 – 997) – 991026973 = 1995 × 995007 – 991026973 = 994011992

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

n3 = (n-1)3 + 3n2 -3n + 1
9983 = 9973 + 3 × 9982 – 3 × 998 + 1 = 991026973 + 3 × 996004 – 3 × 998 + 1 = 991026973 + 2988012 – 2994 + 1 = 994011992
