ROUND 1
How long is Manhattan Island compared with California?
Answer: Manhattan Island — 21.6 km. Manhattan Island measures 21.6 km (height), which is about 57.4× smaller than the reference, California at 1,240 km.
Manhattan is about 21.6 kilometres long.
Common miss: players tend to inflate Manhattan Island when it sits beside California — big things get squeezed, small familiar things get stretched.
How wide is metropolitan France compared with Texas?
Answer: Metropolitan France — 1,000 km. Metropolitan France measures 1,000 km (length / span), which is about 1.3× smaller than the reference, Texas at 1,270 km.
Metropolitan France is nicknamed the Hexagon; no side of it runs much beyond 1,000 km.
Common miss: players tend to inflate metropolitan France when it sits beside Texas — 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.
How wide is Hawaiʻi Island compared with Australia?
Answer: Hawaiʻi Island — 150 km. Hawaiʻi Island measures 150 km (length / span), which is about 26.7× smaller than the reference, Australia at 4,000 km.
The Big Island is larger than all the other Hawaiian islands combined, and still growing.
Common miss: players tend to inflate Hawaiʻi Island when it sits beside Australia — big things get squeezed, small familiar things get stretched.
