Автор ответа: DariosI

Поскольку параллель - это замкнутая окружность, делящая глобус на части, то частей образованных параллелями будет:
15+1=16 частей
А вот меридианы делят глобус как апельсин на дольки. И сколько меридианов - столько доле и получится, значит 20.
20*16=320 частей всего

Ответ глобус поделен на 320 частей
