# 997 Cubed

997 cubed, 9973, is the number you get when multiplying 997 times 997 times 997. It can also be looked at as exponentiation involving the base 997 and the exponent 3. The term is usually pronounced 3rd power of nine hundred and ninety-seven or nine hundred and ninety-seven cubed. The cube of 997 is a perfect cube because the number is the product of the three equal integers 997. It can be written as 997 x 997 x 997 or in exponential form. Read on to learn everything about the number nine hundred and ninety-seven cubed, including useful identities.

9973 = 991026973
997 x 997 x 997 = 991026973

The inverse operation of cubing 997 is extracting the cube root of 997, explained here. In the next section we elaborate on the cube 997, and there you can also find our calculator.

## What is 997 Cubed

A cube is a three-dimensional shape with 6 equal square faces. Hence, a cube with side length 997 has an area of 991026973.

The sum and the differences of two cubes, for example with side length 997 and 996, can be calculated with the following formulas:

1. a3 + b3 = (a + b) × (a2 – ab + b2) ⇔ a3 = (a + b) × (a2 – ab + b2) – b3
With a = 997, b = 996 and the equivalence we get:
9973 = 1993 x (9972 – 997 × 996 + 9962) – 9963 = 1993 x (994009 – 993012 + 992016) – 988047936 = 1993 x 993013 – 988047936 = 991026973
2. a3 – b3 = (a – b) × (a2 + ab + b2) ⇔ a3 = (a – b) × (a2 + ab + b2) + b3
With a = 997, b = 996 and the equivalence we get:
9973 = (9972 + 997 × 996 + 9962) + 9963 = 994009 + 993012 + 992016 + 988047936 = 991026973

As follows from (1), 997 cubed can be calculated from 996 cubed and 997 squared using the identity:

n3 = (2 × n – 1) × (n2 -n + 1) – (n-1)3
9973 = (2 × 997 – 1) × (9972 – 997 + 1) – (996)3 = 1993 × (994009 – 996) – 988047936 = 1993 × 993013 – 988047936 = 991026973

Using the second formula 997 cubed can be also be computed with this identity:

n3 = (n-1)3 + 3n2 -3n + 1
9973 = 9963 + 3 × 9972 – 3 × 997 + 1 = 988047936 + 3 × 994009 – 3 × 997 + 1 = 988047936 + 2982027 – 2991 + 1 = 991026973
