FYI, Arnold is doing a much better job in California than our past few governors. Yeah, he does it a little different, doesn't really follow the traditional politics of government, but that's a welcomed relief from all the bullshit that's in the government nowadays. Are you joking? Arnold sucks ass. No wonder his popularity has plummeted. (restricted) |

This is a math project of mine. |
 It has to do with volume of retangular boxes. As the base increases in size, the height decreases. But it isn't proportional, the height decreases a lot and the volume therefore gets smaller. There's probably some geometry related explanation behind this that I can't remember, and I need help being able to understand this. It's part of a large project. The exact question is: Of all rectangular boxes with surface areas of 216 square inches and bases of x inches by 2x inches, which has the maximum volume? Explain. I know that the box with the smallest base has the largest volume, but.. why?

There's not a pattern.. it just decreases. |
Here's the assignment exactly.. if you need to know some of my work, tell me and I'll type it out. Page 1 Page 2 (#4 is what I'm stuck on, ignore the other 3 questions.)

Mmm.. I'm still going to go with rude. You can go on thinking my sense of humor sucks, and I can think the same about you! |
 Your "joke" fails anyway, nobody laughed.

I could log in here during tutorials at my school, but not all classes have computers with internet access. Only one of my teachers did in her room last year. So if I went there for tutorial and was able to grab a computer, I could come here and post. |
 But.. that's about it. (restricted) |

Wow. |
 I solved to find the volumes a different way.. Ashley helped me quite a bit. If you look on page one that I linked to in my previous post, if gives you a formula: 216=x²+x²+4xh. In problem 4 that I'm stuck at, the base isn't square any longer, so you have to change the formula accordingly: x(2x)+x(2x)+2(xh)+2(xh), which can be simplified to 216=4x²+6xh. That's the formula I used to find the volumes of all the boxes, now rectangular. Then I went through, plugging in all the x bases, to get the height. Enter confusion. ..Wait, I haven't even FOUND the volume yet, only the height. CRAP. So blackhole89... I need to use V=x*2x*n=2x²n to find the volume, with n being the height? I don't really understand all that you said, but it's just because I suck at math horribly. =[ And to answer you, I'm in 11th grade, Math Analysis AKA Precalculus.

I don't remember problems like this, but I don't remember much of anything in math soo.. I might have before. Certainly nothing this complicated. |
So what I'm not understanding.. the formula to find the volume using the height? On the first page I linked to, they give an example for how to find the volume with a square base, I just never realized that. D'oh. It was late last night. So. 6√2*4√2*3√2 = 144√2. I don't understand what that is.. you already solved for the volumes? I'm sure when Ashley gets on she can help explain what you're saying, I'm just too poor at math to understand it.

Happy birthday Reid. |
It's hard to think you're only 15. I would have guessed older.

Originally posted by Danielle Okay, now I've solved for volume.  I had a blonde moment and forgot to solve for volumes before, I was looking at the height as volume. I realized it now, and I did that work. As the height increases, the volume increases. What I still need to know is WHY. I have to explain why it does this, and I have no idea. I did the math already, that's not what I'm looking for, but thanks for all that effort blackhole89. You made me realize all I had was the height.  So, when I changed everything to meet the x by 2x base(which is different from the chart on page 2, which represents square bases only), I got new heights. Then by plugging the heights into x(2x)h, I got the volumes. Erk, you're solving for volume of square bases, which isn't what I need for this problem. Read #4, not the chart. Blackhole, you were literally solving for the volumes, which is what I didn't do at the time, which was why I didn't have a clue what you were doing. Now I've done that, I just needan explanation as to why the volume changes, why the maximum volume is different with a rectangular base than it is for a square base. Why does the volume increase as the base increases and height decreases? And at 4 it's the biggest, and after that it decreases again..? The surface area is the same, it never changes, but the volume changes. I have to explain this in words, and I have no clue how. Here's my results for volume: x --------------- h ------------------- volume 1 ------------- 35 1/3 --------------- 70.667 1.5 ------------- 23 ------------------ 103.5 2 -------------16.667 --------------133.334 2.5 --------- 12.233 ------------- 159.163 3 --------------- 10 ------------------- 180 3.5 ---------- 7.952 -------------- 194.824 4 ----------- 6 1/3 --------------- 202.667 4.5 ---------- 5 -------------------- 202.5 5 ----------- 3.866 ----------------- 193.3 5.5 -------- 2.878 ---------------- 174.119 6 -------------- 2 --------------------- 144 6.5 -------- 1.205 --------------- 101.823 7 ----------- 10/21 -------------- 46.648 Anything beyond this has a negative height, so forget those. 4 has the maximum volume, but WHY?

Because people feel compassion and sympathy. And have hearts. |
Most people.

It takes me about that long to fall asleep as well. It's not a big deal, certainly not severe enough for pills. |
