Utilizing dimensional analysis find the number of inches in a kilometer given that 1 inch equals 2.54 cm

To solve this problem, separate it into chunks that you know. You know that there are 2.54 centimeters in 1 inch. You know that there are 100 centimeters in 1 meter. You know that there are 1000 meters in a kilometer. Therefore, we'll convert in this order: 1) from kilometers to meters, 2) from meters to centimeters, and 3) from centimeters to inches.

1) 1km * 1000m/1km

= 1000m

2) 1000m * 100cm/1m

= 100000cm

3) 100000cm * 1in/2.54cm

≈ 39370in

So, there are approximately 39370 inches in a kilometer.
