3x3 help please

[trisheart]

Hi all, I am new here. I am a little confused on the best way to express a measurement. Is it three feet cubed? three foot cubed, 3'x3'x3', three feet by three feet by three feet, three foot by three foot by three foot? I would also like to know how I should put the same (approximate) measurement to follow in metric - (1mx1mx1m). I am really not sure why this is confusing me but it is. Many thanks.

Sorry, me again. I think rather than cubic I will go with " both back and sides should be ..." but again, should I use words or digits? If it should be words feet? or foot? I have seen it expressed both ways.

I don't really have a precise answer but I don't think it's altogether fair to get no replies to a legitimate question. I would say whatever is the most commonly written way when you google it, would probably be at least acceptable. In this sense, you are probably writing more of a marketable copy, as opposed to a mathematical theory, thus, you would want it to be understood by the most people.

Hi!

I would just go with "All sides should measure X feet". It's short and simple. Spelling out small numbers is very common, but I don't see a real problem if you actually use the number. It would be cool to include metres as well if you are targeting an international audience. I always get confused with dimensions given in different metric systems!

Thank you both for your answers. Mnicol, What you said makes complete sense - why didn't I think of it? I went ahead and submitted with 3'x3'x3' as it just looked tidier. It is still in review so I may edit it - or just leave it. Thanks again for your replies.

I don't really think you'll have a problem with your version. It's a widely acceptable way of expressing measurements, so you probably don't even have to worry about it.

Good luck!

Thanks again. Just replying in case anyone else comes up with something similar. The 3'x3'x3' came through review without comment.
