213 листов
Объяснение:
1. смотрим в таблице плотность железа (7 800 кг/м3)
2. считаем объем 1 листа при заданных размерах. Не забываем переводить все в сопоставимые единицы (я перевел в метры, чтобы сразу в ответе получить м3)
V = 2 * 0,6 * 0,004 = 0,0048 м3
3. считаем вес 1 листа железа
M = 0,0048 * 7 800 = 37,44 кг.
4. определяем количество листов. Делим общую грузоподъемность на вес 1-го листа. (Опять же, переводим в сопоставимые единицы)
8 000 / 37,44 = 213,68 листов
(ну, на заводе или на стройке, специально никто лист резать не будет, чтобы по максимуму загрузить лифт, поэтому 213 листов)
