Final answer:

By converting the room height from meters to millimeters and dividing by the thickness of a penny, we find that approximately 2000 pennies are needed to reach a ceiling that is 2.30 meters high.

Step-by-step explanation:

To find the number of pennies needed to reach the ceiling in a room with a height of 2.30 meters, we can divide the height of the room by the thickness of a single penny.

Given that a penny is 1.15 mm thick, we can transform the unit of the height of the room from meters to millimeters as follows:

2.30 m = 2300 mm.

Now, we will divide the room's height in millimeters by the thickness of a penny to find the total number of pennies required.

Total number of pennies = Room height in mm / Penny thickness in mm

Total number of pennies = 2300 mm / 1.15 mm

This calculation results in approximately 2000 pennies needed to reach the ceiling.
