I'm frustrated, I don't know how to do this
That's because it's poorly written. What the hell dimension is "front" supposed to be?
sterile hound
That doesn't help me. Is that width or depth?
bleak zodiac

width

Okay, now. "Side face perimeter of smallest area is 210 cm." That's... not even a sentence.

The perimeter of what is in green is 210 cm
sterile hound
...you sure about that?
bleak zodiac
Yes sir
sterile hound
I don't know how you can be.
bleak zodiac
I don't know how you can be.
I had already asked my teacher for help but he gave me a very empty explanation of how to solve it but everything I say is according to what he explained to me.

What's the formula for volume?
bleak zodiac
What's the formula for volume?
V = Height * length * Width (I suppose that the length should be obtained with the perimeter of the lateral face?)
sterile hound
V = Height * length * Width (I suppose that the length should be obtained with t...
Let's not skip to the end. So we have a formula for volume. Now we need to get this formula in terms of a single variable.

This what I did is correct?

This what I did is correct?
Almost. Tripped at the finish line.

Almost. Tripped at the finish line.

About this, do I have to change the h to w in the function?
sterile hound
About this, do I have to change the h to w in the function?
Well, no. You have to do more than that. And really, that's a dumb requirement. It's basically just a bunch of arbitrary algebraic shuffling on everything you already worked out.

You can't do b until you're done with a.
bleak zodiac
You can't do b until you're done with a.
Ok, what else do I have to do?
sterile hound
Ok, what else do I have to do?
...rewrite it in terms of w.
Which is actually a bit simpler than I thought before.
Just find the thing with h and w in it, solve for h in terms of w, then replace every h in what you have with that.
bleak zodiac
...rewrite it in terms of w.
like that?
bleak zodiac
Why are you doing b? I told you we were still on a.
Ok, I'm writing it, is this correct?
bleak zodiac
sterile hound
...what?
bleak zodiac
Okay, yeah.
Did I do it right?
bleak zodiac
I mean, do I do the sum but leave its negative value?
sterile hound
...you're asking me how to add negative numbers together?
You're doing calculus and you need to ask how to add negative numbers?

Sorry
sterile hound
And now an unsolicited friend request from someone who just joined the server who I just met. You are not earning any points with me here.
sterile hound
Im just in need of help
Then why do you insist on only asking for it in wrong ways?
limpid birch
I just joined the server
Idk how things work
Ive been stuck for hours and i just thought logically there might be a discord server for maths
I searched on google and was led here
Please man
Just help me
sterile hound
And you didn't think to just look around for five minutes? Or ask in somewhere like #geonosidan-prison-complex "How do I use this server?"
limpid birch
Are u going to help me or not bro
If ur not going to stop wasting my time please
On my behalf its my mistake idk how to use ur server
But i need help with a single question man
bleak zodiac
So now find the zeroes of the derivative.

Stop hijacking someone else's thread.

Yes, because that's what you're doing.

Is that rounded? I don't think it should be a rational number.
bleak zodiac
Is that rounded? I don't think it should be a rational number.
When both numbers are positive, what does it mean?
sterile hound
By my math, it's 75 +/- 5 * sqrt(59). Which... is always positive.
But you want to specifically find the maximum.
Actually, wait.
It seems to me like the maximum is... like, the limit as w goes to infinity?
At least in terms of the function we actually got.
Because it's a cubic with a positive lead term.
,w graph y = x^3 - 225x^2 + 12600x

bleak zodiac
I don't understand very well, one of the numbers was supposed to be negative because we are dealing with a magnitude but it was both, so which one should I take?
bleak zodiac
So... what interval are we actually supposed to find the maximum on?
Sir, so what am I supposed to do or what number should I pick?
sterile hound
Sir, so what am I supposed to do or what number should I pick?
Not a sir. Anyway, hmm...
Wait, dammit. I think you messed up the initial function.
bleak zodiac
Not a sir. Anyway, hmm...
Thank you very much for the help, I already managed to do a large part of the points, I only need the last one
