What Does a³ – b³ Represent?

The expression a³ – b³ is a classic example of the difference of cubes, a fundamental algebraic identity used across mathematics, science, and engineering. The difference of cubes formula states:
a³ – b³ = (a – b)(a² + ab + b²)
This identity helps simplify cubic expressions and solve polynomial equations efficiently.

In our case,
a³ – b³ = 1062,
a value that results from multiplying 6 by 177.

Breaking Down 6 × 177 = 1062

First, let’s clarify the right-hand side:
6 × 177 = 1062
This multiplication is straightforward:
177 × 6 = (170 × 6) + (7 × 6) = 1020 + 42 = 1062.

So, the equation becomes:
a³ – b³ = 1062,
where (a – b)(a² + ab + b²) = 1062.

Solving for Integer Solutions: Finding a and b

While the equation has infinitely many real solutions, a common challenge is finding integer values of a and b such that their cubes’ difference equals 1062.

Let’s denote:
a³ – b³ = 1062

We search for integer values of a and b where this holds true. Trying small integer values:

• Try a = 10:
  10³ = 1000 → 1000 – b³ = 1062 → b³ = –62 → Not ideal (negative cube)

• Try a = 11:
  11³ = 1331 → 1331 – b³ = 1062 → b³ = 1331 – 1062 = 269 → Yet 269 is not a perfect cube

• Try a = 12:
  12³ = 1728 → 1728 – b³ = 1062 → b³ = 666 → Not a cube

• Try a = 13:
  13³ = 2197 → 2197 – b³ = 1062 → b³ = 1135 → No

• Try a = 9:
  9³ = 729 → 729 – b³ = ? Too small

Now reverse: try b = 8 → b³ = 512 → a³ = 1062 + 512 = 1574 → Not a cube
Try b = 7 → 343 → a³ = 1062 + 343 = 1405 → Not a cube
Try b = 6 → 216 → a³ = 1278 → Not a cube
Try b = 5 → 125 → a³ = 1187 → No

This trial-and-error suggests there may be no small integer solutions, but algebraically we know:
