Final answer:
To find the number of pennies in a stack that is 1 foot high, divide the height of the stack (304.8 mm) by the thickness of a penny (1.55 mm), yielding approximately 197.03 pennies.
Step-by-step explanation:
To determine the number of pennies in a stack that is 1 foot high, we need to know the thickness of a penny. The thickness of a penny is approximately 1.55 mm.
To find the number of pennies in a stack, we need to convert the height of the stack from feet to millimeters. Since 1 foot is equal to 304.8 mm, a stack that is 1 foot high is equal to 304.8 mm.
Now, we can divide the height of the stack (304.8 mm) by the thickness of a penny (1.55 mm) to find the number of pennies. Using this calculation, we get:
Number of pennies = 304.8 mm / 1.55 mm = 197.03 pennies
