Hi all I am stuck on this problem

"A rectangular truck platform has dimensions of 2.10 meters and 3.25 meters . In the truck there are placed cubic pieces with side of 65 cm untill the height of 2.6 meters
a) how many pieces are in this truck
My answer is nonsensical 0.006 pieces

No its not . All there are mathematical equations formatted in Mathematica . If you dont want to help please dont post in my question instead of trolling

It may be a great tool for solving problems, but not for presentation of the solution, IMHO.
What I am looking for:
The number of pieces is determined by this formula: xxx
The volume of a piece is determined by this formula: xxx
The volume of the load is determined by this formula: xxx
Therefore, the answer is this: xxx

If the answer is off by several magnitudes, you probably have a mistake in units.

Literally all you are talking about is in my screenshot . If you have bothered to read my answer you would have seen all you are talking about is already there . Are you here to troll people ?

It's perfectly reasonable to present a solution written in a certain format/code to people familiar with this code. E.g. I use C programming language at work. I would not think twice about using it to communicate a solution to my coworkers. However, I would try to use a more descriptive language when presenting it on a forum used by a wide range of people.
Sure, if I spend some time analyzing your solution I can figure out the syntax, etc. But it would've been nice not to.
Your piece volume is in cm3. It seems like you are converting it to cubic meters by dividing by 100. This is incorrect. 1 linear meter is 100 cm. 1 cubic meter is not 100 cm3.

lev888 has identified the main error, namely the incorrect conversion to cubic meters.

Another potential error, which happens not to matter here, is that you should at least have checked that the pieces can in fact be stacked up to exactly 2.6 meters. They can, because 2.6 m = 4*0.65 m. In another problem, that might not have been true.

As for the format in which you showed your work, I have to say that Mathematica is not intended as a means of communication, so I think your use of it is inappropriate if only because it's rather bulky; but I just choose to ignore questions shown in this way. You are probably losing opportunities to get help, just as you would if you posted the problem untranslated in your language. On the other hand, there are people here who are fluent in Mathematicese, and they might have their own opinions.

Good point. I meant to check that and the platform dimensions. And there we are not as lucky - 210 is not a multiple of 65.

What are you talking about . I have not used C code . I just used a very descriptive language who can be understood by anyone claimed to be versed in any kind of equation reading . Its just a bunch of equations with their units . If you can read equations i dont think you should try to ever answer my questions.
 
Perhaps you are not clear on the meaning of the word "explain". Showing the calculations you did does not tell us why you did those calculations.
