Therefore your model's final length and width will be approximately 141.42% greater, and the scale will be about 1:51, because 72 / 1.4142 ~= 50.91.

Regarding sturdiness, if the gramature is the same, the weight scales with area, therefore is 200% of A4 and your model will be 50% as sturdy because sheet strength is roughly proportional to thickness, which is the same.

*remember, width x height = area, therefore if area doubles, linear dimensions increase only by sqroot(2)
so in english - floppy models
