volume and SA of a cubeexpress the edge length of a cube as a function of the cubes diagonal length d. then express the surface area and volume of the cube as a function of the diagonal length. #2 20130124 07:42:31
Re: volume and SA of a cubeskylor: You keep posting questions and then give no response to what I'm offering. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #6 20130124 08:06:38
Re: volume and SA of a cubeThat cannot be right. You are calculating a distance so it should not have a cube term in it. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #7 20130124 08:14:03
Re: volume and SA of a cubeok but im confused because there are no numbers. am I just supposed to give the forumula #9 20130124 08:28:19
Re: volume and SA of a cubehi skylor
Yes.
Now you are getting closer. So now rearrange this to get x in terms of d. That will be the formula l(d) for Q1. Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #12 20130124 08:43:43
Re: volume and SA of a cube
I disagree. So There is a 'theory' in physics that covers the 'dimensions' in formulas. In this case it says You cannot have I suggest you post your other answers for these questions so I can check them.

Re: volume and SA of a cubethese are the formulas I am using #14 20130124 09:02:40
Re: volume and SA of a cubeI have seen these already. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #15 20130124 09:11:56
Re: volume and SA of a cubeI replaced x with d in those problems. Is that what was wrong? #16 20130124 09:17:11
Re: volume and SA of a cube
Yes. Let's say that x = 5. Then d = √3 times 5 = 8.66,,,, You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #19 20130124 09:25:24
Re: volume and SA of a cubehm ok thanks. I think if I know the formula I should be ok.
