That's going tlo depend on how many coins you want in each stack. Was there
something else along with the question that you're not telling us ?
5,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
1 quarter, 6 nickels, and 1 penny equal 56 cents.
56 kilometers=56,000,000 millimeters
Assuming the question refers to US dollar coins: Each current US $1 coin weighs 8.1 grams. There are 453.6 gm in one US pound, so the formula is 453.6 / 8.1 = 56 coins.
Coins are measured in metric units so there's some arithmetic involved. SBA coins (also the newer "golden" dollars) weigh 8.1 gm each. A US pound is about 453.6 gm so there are 453.6/8.1 = 56 SBA dollars per pound. So 50 pounds of dollar coins would be worth 56 x 50 = 2800 dollars.
Two dimes, five nickels, and one penny.
US coins are measured in metric units so you have to start with the fact that a US pound is 453.6 gm.$1 coins weigh 8.1 gm so a pound of dollars is 453.6 / 8.1 = 56 $1 coins, or $56.Dimes weigh 2.27 gm so 10 lbs would be 10 * 453.6 / 2.27 coins = 2000 ten-cent coins, or $200Nickels weigh 5.00 gm so 30 lbs would be 30 * 453.6 / 5.00 = 2722 five-cent coins (rounded to the nearest nickel), or $136.10
There are 56 of the dollar coins in a pound, but as they are not bullion, it is not especially relevant. The coin weighs 8.1 grams and there are 453.6 grams in a pound.
2 quarters, a nickel and a penny.
A fifty cent piece and six pennies.
56 of them.
