ROUND 1
How long is Japan compared with Greenland?
Answer: Japan — 3,000 km. Japan measures 3,000 km (height), which is 1.1× as big as the reference, Greenland at 2,670 km.
Japan’s island arc extends around 3,000 kilometres.
Common miss: players tend to compress Japan when it sits beside Greenland — big things get squeezed, small familiar things get stretched.
How long is Manhattan Island compared with an acoustic guitar?
Answer: Manhattan Island — 21.6 km. Manhattan Island measures 21.6 km (height), which is 21600× as big as the reference, an acoustic guitar at 1 m.
Manhattan is about 21.6 kilometres long.
Common miss: players tend to compress Manhattan Island when it sits beside an acoustic guitar — big things get squeezed, small familiar things get stretched.
How wide is the contiguous United States compared with the Moon?
Answer: Contiguous United States — 4,500 km. The contiguous United States measures 4,500 km (length / span), which is 1.3× as big as the reference, the Moon at 3,474.8 km.
The lower 48 stretch roughly 4,500 kilometres coast to coast.
Common miss: players tend to compress the contiguous United States when it sits beside the Moon — big things get squeezed, small familiar things get stretched.
