Recalling the Difference of Cubes Pattern for Volumetric Tank Analysis

An apprentice training coordinator is drafting an instructional manual for field technicians who measure industrial storage tanks. The difference in volumetric capacity between two pressurized cylinder prototypes is represented by the algebraic expression (x+5)364x3(x + 5)^3 - 64x^3. To simplify calculations for field reports, the manual instructs technicians to factor this expression using the difference of cubes algebraic pattern.

As part of the technical writing team, write a short explanation to be included in the training manual that accomplishes the following:

  1. State the standard difference of cubes factoring formula: a3b3=(ab)(a2+ab+b2)a^3 - b^3 = (a - b)(a^2 + ab + b^2).
  2. From the given expression (x+5)364x3(x + 5)^3 - 64x^3, clearly identify the mathematical terms representing the cubic bases aa and bb to be used in the formula.
  3. Show how these identified bases are substituted into the first binomial part of the formula, (ab)(a - b), and state the resulting unsimplified expression.
