Question

Using dimensional analysis convert 5 km to centimeters.

Answer 1

5km = 500,000cm

Step-by-step explanation:

5km 1000m 100cm

1 km 1m

(The underline represents division)

Step 1: Multiply all the number on the top row including the 5. 5 x 1000 x 100

= 500,000

Step 2: Divide by the bottom row. 500,000 / 1 = 500,000 and then 500,000 / 1 = 500,000

Final answer: 500,000cm
