Talk:Cuboid

message: Pardon me for being stupid, but is a square cuboid not only one square face?  If it has two square faces then does its conjunction on each edge not require that the third is therefore also a square?
:Care to sign your post (;-)? The sentence in the article is correct. Hint: A cuboid has six faces. But you are thinking along the right line (:-). --RainerBlome 06:36, 23 July 2007 (UTC)

: , or in a shortest calculation, 2(a+b)h+ab.
but 
# They must mean "2((a+b)h+ab)
# The h is undefined, but h=c would fix it
# It needs some justification of the logic of "shortest": what assumption is involved as to, e.g., ratio between time do multiplications and addtiongs, and what is the domain where that matters? This isn't an optimum-computation manual, and the effort of remembering a less intuitive formula is unlikely to be repaid.
Let's hear what they have in mind here.

"A cuboid with integer edges as well as integer face diagonals is called an Euler brick, for example with sides 44, 117 and 240. A perfect cuboid is an Euler brick whose space diagonal is also an integer. It is currently unknown whether a perfect cuboid actually exists."
I think the words length and area are missing.  But it is not my field so I have not changed it  — Preceding unsigned comment added by 130.88.75.48 (talk) 09:40, 5 September 2011 (UTC)

thread_title:  Euler Brick 

message: ... in saying that according to the definitions given on the main page, a square cuboid is not a special case of a rectangular cuboid since the former may have 4 faces which are not rectangles, whereas the latter has all faces rectangles ?  If so, is this definition of a square cuboid intended, or should a square cuboid be defined as a cuboid in which all faces are rectangles and at least 2 are squares - i.e. a rectangular cuboid of which at least 2 faces are squares ?  — Preceding unsigned comment added by 77.96.59.93 (talk) 18:58, 27 November 2013 (UTC)
replies: text: You seem to be under the impression that a square is not a rectangle. While there is some support for that position in the literature, I don't think it's a helpful point of view. A square is a special kind of rectangle, but it is still a rectangle. The square cuboid's square faces are also rectangles, and the square cuboid is also a rectangular cuboid. —David Eppstein (talk) 19:12, 27 November 2013 (UTC)
