you shouldn't have posted it to begin with

as far as your problem, HMT, I am not the best at geometry. This will help with the factoring.. https://www.mathway.com/

I think this is prime, they don't have a GCF

Haha, i'm on that site right now!

And I have it factored, it's (x+3)(x−3)(x−7). but i'm not sure what to do after that.

texaschic101 · Answer

mathway is showing this as the factored form :
(x + 3)(x - 3)(x - 7)

I think one has to be length, one width, and one height. But I am not 100% sure. Because to find the volume of a rectangular box, you just multiply LWH. I am sorry but I am really not good at this

anonymous · Answer

yea, I got it factored. But if I multiple it then i'll get the equation i originally started with. That's ok, I only needed the dimensions... I think i got them. :)

sorry I wasn't much help. :(

anonymous · Answer

It's ok.

the_fizicx99 · Answer

I'm not sure what you're trying to find, but the formula for volume is, V = lwh, you factored it into 3 piece which is what you needed? what threw me off is the 7x^2 >.> doing mental math i saw 7 is prime ;-;, means there's 7 x^2 .-.
