A lot. ;)
The answer will depend on pennies from which country!
50
12
Assuming that the 14 inch box is square, you could fit a circle inside with a 14 inch diameter.
91 with .79 cubic inches to spare.
729 of them!
1,728
1,000-3,000 pennies
60 - 70
50,000
Approximately 7,500 pennies could fit in a three gallon jug.
To fit 5,000 pennies, you would need a box that can accommodate approximately 25 pounds, as 5,000 pennies weigh about that much. Given that a penny has a diameter of about 1.9 cm and a thickness of 1.52 mm, the volume occupied by 5,000 pennies would be roughly 1,000 cubic inches. A box measuring around 12 x 12 x 12 inches would be sufficient to hold the pennies, allowing for some extra space.
