1) they all weigh a pound.
2) 1,000,000 pieces of $1 shaped paper
Wrong on both counts.
You wouldn't need any paper. $1 bills are printed on linen.
Close enough. No wood pulp used - it's 75% linen, 25% cotton. Wood pulp paper bills wouldn't last a month in heavy circulation.
1) Which weighs less: a pound of feathers, a pound of bricks, or a pound of gold?
Trick question. a pound of gold weighs less. Gold is weighed in Troy pounds, which are about 18% less than regular pounds.
The troy scale is used only for precious metals, gemstones, things along those lines. The avoirdupois scale is used for common items, including body weight.
An avoirdupois ounce is 28.35 grams and there's 16 ounces to one avoirdupois pound. Total 453.6g.
A troy ounce is 31.1 grams but there's only 12 in a troy pound. Total 373.2g. 17.72% less!
New questions, and no looking at the US Treasury website!
True or false: it costs more than a dollar to print a one dollar bill.
True or false: the US Mint still makes copper pennies.
BTW: ingenious answer, AceG!
