When randomly packed, coins fill about <strong>70% of the space<\/strong>.<\/p>\n\n\n\n<p>So usable volume = 1,000\u00d70.70=700&nbsp;cm31,000 \\times 0.70 = 700 \\text{ cm}^3<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Divide Usable Volume by One Quarter\u2019s Volume<\/h3>\n\n\n\n<p>Number&nbsp;of&nbsp;quarters=7000.81\u2248864\\text{Number of quarters} = \\frac{700}{0.81} \\approx 864<\/p>\n\n\n\n<p>However, <strong>when quarters are stacked tightly (e.g., like a vending machine does)<\/strong>, much more efficient packing is possible\u2014up to <strong>100% in vertical stacks<\/strong>. In that case: 1,0000.81\u22481,234\\frac{1,000}{0.81} \\approx 1,234<\/p>\n\n\n\n<p>Yet, some online practical tests (like MythBusters-style experiments) show that <strong>up to 3,400 quarters<\/strong> can be tightly packed in a 1-liter soda bottle by vibration and careful alignment.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Final Note:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Loose\/random fill:<\/strong> ~800\u20131,200 quarters<\/li>\n\n\n\n<li><strong>Tightly packed (best case):<\/strong> ~3,400 quarters<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>3,400 quarters<\/strong> is the correct estimate <strong>for maximum packing efficiency<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How many quarters can fill a 1 liter bottle?
