I. Understanding the Conversion Factor

Q: What is the basic relationship between centimeters and feet?

1. Inches to centimeters: 1 inch = 2.54 cm
2. Inches to feet: 1 foot = 12 inches
3. Combining the conversions: 1 foot = 12 inches 2.54 cm/inch = 30.48 cm

Therefore, 1 foot is equal to 30.48 centimeters. This is our crucial conversion factor.


II. Calculating 40 cm in Feet

Q: How do we convert 40 centimeters to feet using the conversion factor?

A: Now that we know 1 foot = 30.48 cm, we can set up a simple proportion to convert 40 cm to feet:

x feet / 40 cm = 1 foot / 30.48 cm
```

Solving for 'x' (the number of feet):

```
x = (40 cm 1 foot) / 30.48 cm
x ≈ 1.312 feet
```

Therefore, 40 centimeters is approximately equal to 1.312 feet.
