Thanks I have added that one to reference material too :)

Thanks guest

I have now worked out exactly what it can do but it does look interesting.

I am sure if could be used by people on this forum.

Do you use it yourself?

I have added this reference to our 'reference material' sticky topic.  (under calculators)

dimensions    4, x+1,  x+11    all in cm        V=924cm^3

so

\(4(x+1)(x+11)=924\\ (x+1)(x+11)=231\\ x^2+12x+11=231\\ x^2+12x-220=0\\ \)

The rest is pretty much already done.    

I don't get what you are asking.

I suggest that you use this site. It is really good for questions like this.

How many positive integer divisors of 23,328 are perfect cubes?

23328^(1/3) = 28.573218935427587   Well less than 29 anyway.

1 is ok

factor(23328) = 2^5*3^6

\(2*2*2*2*2\quad * \quad 3*3*3*3*3*3\\~\\ 1^3,2^3,3^3,6^3,9^3,18^3 \;\;\text{that seems to be it.} \)

I just got those from visual examination of the factors.

So that is  6 of them.

Good logic PM     

Oh and you can appologize for wasting CPhills time too! 

What do you mean 'nevermind!'

You asked a question and CPhill went to a lot of effort to answer it for you.

The next thing for you to do is to say thank you! 

Thanks Chris,

Sometimes we just get on the wrong track. 

It was a nice little question actually :)
