with what materials should i build a scale model of the pyramids?
i have a project on scaling down the pyramids than building it, with what materials do u think i should build the scale model of the pyramids?
rigid styrofoam, it is light, easy to cut and shape and fairly cheap
In the world of model railroading, scale means the ratio of a model to the real-world prototype. For example, an HO scale train, with a proportionate size of 1:87, is 87 times smaller than the full-size train on which it is based.
Model railroading uses a variety of scales, which are standardized by hobby associations and other groups. The two dominant "standards" organizations for the hobby are the National Model Railroad Association (NMRA) and the European Union of Model Railroad and Railroad Fans, better known as MOROP (for the word derived from MOdellbahn [German for model train] and EuROPe). MOROP defines and maintains the Normen Europaeischer Modellbahnen (NEM) standards for model railroads.
The most popular scales are: HO, O, N, and Z.
HO (1:87) is the world's most popular scale. (This does not include the United Kingdom, where OO rules.) In the HO scale, 3.5 mm equals 1 foot. Due to the large customers base, manufacturers are producing a broad range of HO products for model train enthusiasts. Model railroading adopted the HO designation because it is (approximately) half the size of the older O scale - in other words, half of O.
O (1:48) dominated the hobby from the 1920s until the post-World War II years. Maerklin, the German toy manufacturer that originated the O scale around 1900, chose the 1/48th proportion because that was the scale for their line of doll houses. O has decreased in popularity because it requires a great deal of space for extensive layouts.
N (1:160) stands for nine millimeter, the size of the N scale's corresponding track gauge. The exact gauge, however, is 8.97 mm. N is the world's second most popular scale. N model train hobbyists choose N over HO because the smaller one allows for larger layouts to be built in limited available space.
Z (1:220) until recently was the smallest commercially available scale in model railroading. It is popular with apartment dwellers and others who have very limited space available for their layouts. Z is the fastest growing scale in the hobby.
Other common scales:
G (1:22.5), also known as garden scale, is for trains that can be used outdoors.
OO (1:76.2) is the most popular scale in the United Kingdom.
The smallest model train scales:
TT (1:120) stands for "table top" and is popular in Europe, especially in Germany and some countries of the former USSR.
T (1:450), which originated in Japan, is the smallest commercially available model railroading scale.
Others include several outdoor sizes (some large enough to carry passengers), steam model trains, wide gauge, and more.
