I want a dimension of Venetian gondola?

This website http://www.hobbyworldinc.com/woodship100.html

has a model that looks good and they say it is 1/20 scale and is 21.5" long which would make the original 430 inches or 35.8 feet.

Wikip has links http://en.wikipedia.org/wiki/Gondola including this one http://www.gondolavenezia.it/homeng.asp the official site

By looking up the length of the oars, you could probably scale dimensions off of photographs.

This page http://www.veniceboats.com/eng-models-gondolas.htm has a number of models in various scales, giving the sizes, again you might scale other dimensions. From that page this page and others http://www.veniceboats.com/eng-designs-boats-gondo...

Show small versions of detailed drawings showing all the profiles, etc.

In string theory, In addition to the three normal spatial dimensions, there are 6 spatial dimensions curled up into a class of shapes called Calabi-Yau manifolds. These are the dimensions that strings vibrate in. M-theory added an additional spatial dimension which is believed to be a small dimension that separates branes (3-branes in particular). There is absolutely no requirement that dimensions be perpendicular to each other - they just need to be independent degrees of freedom. Don't think that just because our three dimensions in flat space are orthogonal then all dimensions have to be orthogonal.
