To compare the lengths, we need to convert everything into the same unit. Let's convert everything to inches:
-
6 yards:
- 1 yard = 36 inches
- So, 6 yards = 6 × 36 = 216 inches
-
19 inches:
- Already in inches, so it remains 19 inches.
-
2 meters:
- 1 meter = 39.37 inches (approximately)
- So, 2 meters = 2 × 39.37 ≈ 78.74 inches
-
300 centimeters:
- 1 centimeter = 0.3937 inches
- So, 300 centimeters = 300 × 0.3937 ≈ 118.11 inches
Now, let's compare the lengths in inches:
- 6 yards = 216 inches
- 19 inches = 19 inches
- 2 meters ≈ 78.74 inches
- 300 centimeters ≈ 118.11 inches
The longest length is 6 yards (216 inches).
