It would take 10 trillion pennies to make 10 billion dollars. This is a large amount of pennies. It would be enough to fill an entire 2,500 square foot house from top to bottom.

Many countries use a penny in their coinage, but they are of different sizes. You need to specify which country.
144 inches in one square foot. Since it is a square foot you would take 12 inches time 12 inches to get 144.
The diameter of a US penny is 0.75inches. There are 256 pennies in a square foot
256 pennies in one square foot. 16pennies in a row = 12 inches
There are 49,152 pennies in a cubic foot. That's a little over 300 pounds of pennies.
There are 304 pennies in a square foot 16 pennies = 12 inch line. 16 X 16 = 256 *************************************************************** Despite the difference of 48 pennies between the two answers above, both answers could be correct. If pennies were square, then answer #1 would be incorrect. Answer #2 relies on the pennies being arranged in a grid pattern. 16 x 16 = 256. However pennies are circular and can be "nested" when arranged. That means that the first row would be 16 pennies. The second row would be 15 pennies, the third row would be 16 again, then 15 again, etc. Because of the nesting, additional rows can be added in the same square foot of space. I haven't tried to see how many more pennies could be accommodated by this nesting (or "staggering") so I don't know if the 304 is an accurate count in such a case. However there would certainly be more pennies per square foot in a nested arrangement than in a grid arrangement.
