Answer:
Maximum height of quarter tower = 9.6 inches.
Step-by-step explanation:
The thickness of a quarter = inches
Weight of a quarter = 1 ounce
The maximum weight that could safely hold = 3 pounds.
<u>The conversion factor for ounce to pound is 1 ounce = 0.0625 pound</u>
The number of quarter used in the tower = no of ounces equivalent to 3 pounds.
No of ounces equivalent to 3 pounds =
No of ounces equivalent to 3 pounds = 48
So the height of quarter tower = 48 \times inches
= 9.6 inches.
The original side length was 12m therefore the perimeter was 36m. 12/4 is 3 so the perimeter is now 9, and the difference between them is 27.
