Pushing Pennies
On a square of paper measuring 38.1 mm. a side, you can fit exactly four pennies. Hmmm.... I wonder how many you could fit on a standard sheet of notebook paper (8.5 in. by 11 in., or 215.9 mm. by 279.4 mm.).
Pick a method and estimate the number of pennies you could fit, then tell why you think your estimate is high or low. Be sure to show all your work. | | |
