Dude,A cuboid is something which has different length,breadth and height,so 4x4 and 5x5 are cubes,not cuboids,thats why there are called Big cubes....not big cuboids

They are just the same as 3x3 cubes but with a bigger volume

Technical definition of cuboid: a rectangular parallelepiped.
A parallelepiped is a six sided figure in which each side is a parallelogram (a four-sided figure in which pairs of opposite sides are parallel)
A rectangle is a parallelogram with four right angles.
Since a square has four right angles, it is considered a rectangle. If I see a square, I can correctly say, "that is a rectangle."
Thus, when a six sided figure has each side being a square, each side is also a rectangle, and the figure can be called a cuboid.
4x4x4's and 5x5x5's are cuboids.

Do you seriously not realise that things can fall within multiple categories?

a square is a type of rectangle. A rectangle is a four-sided polygon with all four angles being right angles. A square is four-sided, and has four right angles. If I see a square, I can correctly say, "that is a rectangle."
Same thing with cube and cuboid.

I am curious if you have ever taken geometry in school?

First off, you broke a few forum rules, language, flaming, and sorta telling someone to search

Second I hate that site the tiny links to, since everytime I go there, my harddrive starts up, which is unusual.
And since it isnt contributing to the forum, I think it should not be allowed for forum use.
Not tinyurl, but the site that tinyurl links you too

cuboid - A Six sided object all right angles, all six sides are rectangles
square - a quadrilateral with four equal sides and all right angles
cube - a 6 sided figure with squares on each side
rectangle four interior right angles

While a square is a rectangle, technically a 3x3, 4x4. and 5x5 are considered cuboids.
In cubing equal sides are called cubic, (ex. cubic 3x3x7 or cubic 3x3x5) instead of the non cubic ones,
and cuboid usually refers to every thing cubing, except the minxs, and such. But generally I have seen cuboid refer to such items as the 3x4x5, or the 1x2x3
It could be a definition that got twisted to have a different meaning when it is used as a cubing turn.
Ex. permutation - the true defintion of permutation has nothing to do with moving anything to the right spot, yet in cubing that is what it does. It has similar definitions, but it is not specific.

First off, I apologize for all of my posts earlier today, I was sick and in a bad mood (still am, but am now making a conscious effort to sound a bit more civilized..). I have completely edited the post.

Not trying to come across with extreme anger or anything like that (remember, I'm trying to be civilized), but I would like to point out that that is the first time I have used it, and others use it a lot, so it is nice that you direct your irritation with it at me. (but of course, I can understand it because I haven't exactly been nice to you...ever) In fact, vcuber used it exactly one post below the post from ilikecubing that started this in the first place:

This is because the term "cubic" refers to being in the shape of a cube. As I am sure you know, a cube is a special type of cuboid in which all sides must be squares. As we both have pointed out, they can still be called cuboids. However, any cuboid cannot be called a cube. We do not regularly call the 3x3x3 or 4x4x4 'cuboids' for the same reason we do not regularly refer to a square as a rectangle; it can be put into a more restrictive set (cube). Items such as a 3x3x4, etc., are referred to as 'cuboids' because there isn't a more restrictive set they can be put into. It really is not a definition that is being twisted to have a different meaning.

Ex. permutation - the true defintion of permutation has nothing to do with moving anything to the right spot, yet in cubing that is what it does. It has similar definitions, but it is not specific.

It may not exactly mean 'moving it to the right spot', but the term permutation certainly is much more strongly related than you seem to think. In that link to thefreedictionary, it says "A rearrangement of the elements of a set." Note that here, a specific position of the cube is referred to as a permutation. Going by thefreedictionary definition that i mentioned, the pieces of a cube are 'elements' of the Rubik's Cube 'set'. When we say something like, "PLL: permutation of the last layer," what we really mean is "Correct permutation of the last layer." It is the same thing as saying "that 4x4 solve had PLL parity"; we really mean "that solve had odd PLL parity" or "that solve had a PLL parity problem"

@ubercuber, i wasnt mad, but i have seen those links many time and was just pointing out the site in general, not pointing at your specifically for using it.
I just think that since one of the forum rules is to not tell some one to search,that particular site is not in the forums best interest, in my opinion.

and i get what you were saying about permutation, but the definition was used vaguely to apply to cubes, sorta like cuboid has been in the past.
"A rearrangement of the elements of a set." lol that would also mena that just doing amy move falls under the term permutation, while that is true, I do not think it applies in cubing to just single moves, besides possible AUF lol
"are referred to as 'cuboids' because there isn't a more restrictive set they can be put into" i think that is why everything that isnt a "cube" is called a cuboid. lol. so for cubing perposes - I think cuboid should only refer to rectangular prism where at least one out of height, width, and depth is longer than the other. This is to just simply end the confusion and make classifying cube slightly simpler. >.<

lol
Im fairly sure I could find some Math people that could argue for hours on the subject. >.<

This is correct. Making any move to any cube changes the permutation, it moves from one unique permutation to another unique permutation. I don't know why you are laughing out loud about this. The math definition for permutation is very applicable to the "cubing def'n"

By your definition of cuboid, a cubic 3x3x7 isn't a cuboid. It would be in the same group as 3x3/2x2. I think cuboid can refer to either cubic or non cubic cuboids, and I don't see why you think your definition is best.

I didnt say my definition is best. I was just attempting to simplify things. I agree with you on non cubic and cubic cuboids still being cuboids, but the sq1 is a cube and I would consider it a "cube" so cubic cuboids could double classify as cuboids and cubes, or cuboids modified into cubes. but its whatever. Too many terms get taken to their extremely literal definition, when used as a cubing term. At Least that is my opinion.
 
upon seeing the 2x2,"AWHHHH ITS SO CUTEEEE. i bet its super easy, give it to me."
they can never solve it

or they call the 2x2 the 4x4 because theres 4 pieces on a side
since when does 4x4 not mean 4 pieces by 4 pieces?
its stupid because they all know the regular cube is 3x3

It seems like it should, doesnt it?
If that was a real question, then the answer is no. There are multiple events and sometimes multiple rounds per event. Like the US nationals is like 3 days long.

I know this it was just a funny question my friend asked
