I'm a bit confused at what happened from step 5 to 6. Where did the first s go, and why would the 1/2 be changed to a 3/2? Why is the s squared instead of cubed? I may be stupid here but I'm pretty sure those two equations would have different answers. Why wouldn't the answer be s= the square root of 5?
The algebra on step 5 is correct. I suggest that you copy the expression and then reduce it yourself and you'll see that you end up with the same result
Easy way : Maximum of volume means that the box is cubed , then the surface area S.A=6s^2 , then 10=6s^2 , then s=1.29, then the volume is =1.29*1.29*1.29 =2.152m^3
This video is made to show the technique of using calculus for a max/min type of problem. Yes, indeed for a simple problem like this you can solve it in many other ways, but we want to show examples of simple problems first so you can learn how to apply this technique to more challenging problems.
@@MichelvanBiezen thank you , True, to understand the idea of the topic, it is necessary to start with a simple example, as I see many mathematics curricula start with a topic, but the example related to it contains a lot of complexity and details, so that the student gets lost and does not understand the idea of the topic.thank you again .please could you show us more complex example that can be solved just with your explanation.Because I am studying this subject and I have an exam soon, but there is confusion about using the method. I do not know with what kind of questions I use the simple way and can I use it with all the examples?
There should be other examples in the playlist. We are also working on adding more videos in the various calculus playlists and we will review this topic as well for additional examples.
I'm here because tenten video about how to maximize dps on Genshin Impact lol

Nice work 😊
Thanks 😄

@@MichelvanBiezen Thank you for your reply, God blessed you.
Excellent video!! Thanks
Sir what if it’s not a square base?
This type of problem can be done with different shapes and situations. See the other examples in the playlist.
@@MichelvanBiezen then it is not possible with this one?
Not sure what you mean by that question. Max-min problems can be done on any shape, including the shape in the video.
@@MichelvanBiezen nvm I got the concept. thanks for the help
I'm sorry sir, but in the near-end part. Weren't you supposed to rationalize the radical expression? I think you made a mistake there.
Did you watch the whole video?
@@MichelvanBiezen Yes, and I realized I had the same answer with you even when you did the shortcut. Can I ask how you did that, sir?
Video🎥 quality is very poor
Thank you
Thank you
You're welcome 🙂
