Ответ:

Для знаходження маси чавунної кулі об'ємом 210 см³ потрібно знати густина чавуну. Зазвичай густина чавуну складає від 6,9 до 7,8 г/см³, тому візьмемо середнє значення - 7,35 г/см³.

Маса кулі може бути обчислена за формулою:

маса = об'єм × густина

Замінюємо в формулі дані:

маса = 210 см³ × 7,35 г/см³ ≈ 1543,5 г

Отже, маса чавунної кулі об'ємом 210 см³ приблизно дорівнює 1543,5 г.
