Answer 1

To find the number of centimeters in 1 yard, the best path is:

**yards Right-arrow feet Right-arrow centimeters**

Here’s how it works:

1. Start with 1 yard.
2. Convert yards to feet: 1 yard = 3 feet.
3. Convert feet to inches: 3 feet = 3 × 12 = 36 inches.
4. Convert inches to centimeters: 36 inches × 2.54 cm/inch = 91.44 centimeters.

Thus, 1 yard = 91.44 centimeters.

This path efficiently uses the conversions with the correct units at each step.
