Solution:

Given data:
- Diameter of the well = 150 cm
- Length of the outer edge of the parapet = 660 cm

Calculating the circumference of the well:
- Circumference of the well = π * diameter
- Circumference = π * 150 cm
- Circumference = 471.24 cm

Finding the width of the parapet:
- Let the width of the parapet be 'x' cm
- The outer edge of the parapet will be the circumference of the well plus the outer edge of the parapet on both sides
- 660 cm = 471.24 cm + 2x
- 660 cm - 471.24 cm = 2x
- 188.76 cm = 2x
- x = 94.38 cm

Therefore, the width of the parapet is 94.38 cm.

This means that the distance from the outer edge of the well to the outer edge of the parapet is 94.38 cm on all sides.
