How heavy would be a 1:1 map of the world be?
A sheet of A4 weighs 0.005 kg and has an area of 0.06237m² (210mmx297mm).
The earth's area is 5.10072 × 10^14 m²
So a map, at 1:1 scale, would weigh:
5.10072 × 10^14
--------------- x 0.005
0.06237
= 4.1 x 10^14 kg
or 410 billion tonnes

Assuming the world is a smooth sphere.
