Total volume = Length × Breadth × Height. Empty fraction = 1 − \(\frac{3}{10}\) = \(\frac{7}{10}\).<br><br>&bull; Total volume = 100 × 45 × 60 = 270000 cm&sup3;<br>&bull; Empty space = \(\frac{7}{10}\) × 270000<br>&bull; 270000 ÷ 10 = 27000; 7 × 27000 = 189000 cm&sup3;<br>&bull; 189000 ÷ 1000 = 189 l<br><br>Final Answer: 189
