The British One Pound coin is 3.15mm thick, so 317 or 318 coins should make a metre high stack.
The British One Pound coin is 3.15 mm thick, so a stack of 100 of them would be 315 mm high.
10 centimeters long
100
The answer depends on 6.5 million what, and in what units. A stack in 50 pounds notes will be different from a stack for the same amount in 1 penny coins.
3.2 kilometers or 1.99 miles. each coin is 3.14mm thick, working in old money that's just under 12 1/2 inches per 100 coins, 3000 coins = 30ft = £528,000 per mile £1,056,000 = 2 miles
The Eiffel Tower is 324 metres high to the top of the spire. If your unspecified "pile of One Pound coins" is also 324 metres high, the pile and tower will be exactly the same height.
A dime is 1.35 mm (0.135 cm) thick so a 5 cm stack would contain5/0.135 = 37.04 coins (approx).A dime is 1.35 mm (0.135 cm) thick so a 5 cm stack would contain5/0.135 = 37.04 coins (approx).A dime is 1.35 mm (0.135 cm) thick so a 5 cm stack would contain5/0.135 = 37.04 coins (approx).A dime is 1.35 mm (0.135 cm) thick so a 5 cm stack would contain5/0.135 = 37.04 coins (approx).
A Canadian one dollar coin (a "loonie") is 1.75mm thick and 26.5mm in diameter (actually it is not round - rather,it has 11 curved sides - but the difference should be minimal for our purposes here). If your question is "How many loonies in a stack of coins one meter high?", then the answer is 1000/1.75 = 571.43, or about 571. If your question is "How many loonies laid end to end would be needed to stretch one meter?", then the answer is 1000/26.5 = 37.74, or about 38.
One mile is 1609344 mm. A US nickel is 1.95 mm thick, so a mile-high stack would contain 1609344 / 1.95 = 825,305 coins, rounded to the next-highest whole number. Each nickel is worth 5 cents so the stack's value would be 825305 * 5 = 4126525 cents, or $41,265.25
All US paper money is 0.11 mm thick. Multiplying by a million simply involves moving the decimal point 6 places to the right, so the stack would be 110000 mm high. There are 1000 mm in a meter so converting to a more useful unit, the stack is 110 m high, or about the height of a 40-story building.
12 x 3 / 4 = 9 The stack is 9 inches high.
