Which is not a part of cubing?

a. describing physical attributes of the product.
b. relating your product to something else.
c. telling how your product can be used.
d. identifying an audience for the product.

The answer is indeed D. identifying an audience for the product.

Explanation:

Cubing is a technique that can be employed to help us study a certain topic from six different perspectives. It's a tool that can be applied, for instance, prior to writing. The six perspectives are:

1. Describe: thinking of the five senses, describe the topic or product so that the readers can see or smell it, for example, in their minds;

2. Compare: find the similarities or the differences between the topic and another one;

3. Associate: find memories or thoughts you can relate to the topic;

4. Analyzing: break the topic down into parts and evaluate their connection;

5. Applying: define how this topic or product can be applied or used;

6. Arguing: Discuss the strengths and the weaknesses of the topic or product.

As we can notice, none of the six sides (perspectives) of the cube focuses on identifying an audience for the product. That's why the answer is option D.
