<p>[QUOTE=&quot;rodeoclown, post: 1401825, member: 34005&quot;]I had to guess the radius of the jar but you said it was about 4.5 inches tall, so I guess the radius would be about 1.5 inches, making the diameter of the jar at about 3 inches, that means without calculating the empty space in-between the pennies stacked inside the jar, you could theoretically fit about 443 pennies in a jar of that size by my calculations of the cubic size of a penny, so minus a few with the empty space taken up in how they are stacked (which you can tell by the picture), my guess is, you&#039;re gonna get anywhere between 400-450 pennies out of that jar max.</p><p><br /></p><p>Math is not hard.&nbsp; Pi is your friend.</p><p><br /></p><p>Penny has a .375 inch radius and it&#039;s 0.061023622 inches thick. Jar is around 4.5 inches tall and likely has a 1.5 inch radius (guessing since we don&#039;t know exact size). Do the math, boom, you get 442.854207395 unless my math is off tonight.[/QUOTE]</p><p><br /></p>
