surface area of 3D surface

I have data for 3D points and I have made a surface using points. Is there a way to get surface area of 3D surface.

If you turn the above into sentences instead of bullet points, and you add an opening sentence that asks the user to solve the following problem, then the resulting question would be a solution to itself.

[Walter Roberson]

Create a question with the characteristics given in the following sentences.

Prepare your question that would consist of at least 4-5 sentences.

Write your question that will allow data entry by the user (minimum 2 data).

Include mathematical operations (especially elementwise operations).

Ask to show the result/s as a table and a 2D/3D graph in your question.

The above question has itself as its own solution, and is therefore the solution to the exam question as phrased.

Would our doing your exam for you really help you? Seriously? If you need help that badly, then you should have been studying more and earlier.

And suppose we do your exam for you? How do you feel the other students will feel, those who just got cheated, because they studied for the exam, and did the work fairly? Now they get a comparatively poor grade?

Would your teacher be happy to know that you convinced someone else to do you exam for you?

And then, suppose we do help you to graduate unfairly, having done no work to merit the result? How do you feel some potential employer would feel to know they got cheated, when they realize they had just hired someone with invalid qualifications?

Sometimes it is a good thing for someone to fail. That is the best thing you can learn, that you need to work for what you get, and if you don't make the effort, then you should get exactly what you deserved.

[Walter Roberson]

There are licensed professions such as various kinds of engineers, and architects. The license certifies that the person knows what they are doing, and is not going to make mistakes that can harm people . It would be irresponsible for us to give exam answers to anyone in such a profession.

We do on the other hand, spend a lot of time helping students understand the concepts and the documentation and the error messages -- teaching students that approach us before their exams, helping them learn so that they have the knowledge and skills to be able to write the exams on their own.

Thank you for your help Walter.

[John D'Errico]

We do help. But, the question posed was just an exam question. Though, interestingly, it is now a completely different question.

[Ilayda]

I had a few questions, I handled of the first one, now I asked this and that wasn't my exam question.

[Walter Roberson]

The new question sounds like they want to know How do I determine the surface area of a 2-D surface in a 3-D space.

[John D'Errico]

I know what the new blasted question is! But if we answer the new question, will it again change?

It is difficult to chase a question that constantly changes. Yes. I know that the NEW question is different. But it is inappropriate to post exam questions here. And that was my response to your FIRST question.

If you want to know IF there is a way to get the surface area, the answer is yes.
