ROUND 1
How long is an American football field compared with a Boeing 747?
Answer: American Football Field — 109.7 m. An American football field measures 109.7 m (length / span), which is 1.6× as big as the reference, a Boeing 747 at 70.7 m.
Goal line to goal line is 100 yards; end zones make the full field 120 yards.
Common miss: players tend to compress an American football field when it sits beside a Boeing 747 — big things get squeezed, small familiar things get stretched.
How long is an American football compared with a large pizza?
Answer: American Football — 28 cm. An American football measures 28 cm (length / span), which is about 1.3× smaller than the reference, a large pizza at 35.6 cm.
An American football is measured along its long axis; the pointed ends make it read larger than it is.
Common miss: players tend to inflate an American football when it sits beside a large pizza — big things get squeezed, small familiar things get stretched.
How long is an NBA basketball compared with an American football?
Answer: NBA Basketball — 24.3 cm. An NBA basketball measures 24.3 cm (length / span), which is about 1.2× smaller than the reference, an American football at 28 cm.
An NBA ball is regulated by circumference, about 75 cm, which works out to just under 25 cm across.
Common miss: players tend to inflate an NBA basketball when it sits beside an American football — big things get squeezed, small familiar things get stretched.
