Пошаговое объяснение:

45 - 5 =40 см высота

Объем аквариума равен: V=a*b*h=60*45*40=108000 см³

так как он заполнен до уровня 30 см то объем воды будет

V=a*b*h=60 *45 *30 = 81000 см³

1 литр = 1000 см³

х литров - 81000 см³

х = 81000 :1000

х= 81 л воды в аквариуме если он заполнен до уровня 30 см
