Question 1208737: A jumbo chocolate bar with a rectangular shape measures 12cm in length, 7cm in width, and 3cm in thickness. Due to escalating costs of cocoa, management decides to reduce the volume of the bar by 10%. To accomplish this reduction, management decides that the new bar should have the same 3cm thickness, but the length and width of each should be reduced an equal number of centimeters. What should be the dimensions of the new candy bar?

Let me see.

I need V = length x width x height

Let height = thickness of bar

Length = (12 - x)
Width = (7 - x)
Height = thickness = 3cm

My setup:

V = (12 - x)(7 - x)(3)
You say?

All good work, but remember, new bar is to be reduced by 10%.

.

Your setup in the post was incomplete, since the setup equation was not obtained.

As I see from this post and from many other your posts, your style of work is
to do as few of the job as possible, by reloading the rest of the job to the shoulders of other (tutors).

And then "to make blue eyes" at the end.

Normally, you should make your job in full, from the beginning to the end,
without reminding and elucidation from outside. It is what is expected from you.
