**Example 1****: Convert 180 square inches to square feet.**

**Solution:**

- 180 square inches can be written as 180 x 1 square inch.
- Since 1 square inch can be written as 1 inch x 1 inch,
- 180 square inches can be written 180 x 1 inch x 1 inch.

Therefore, another way to work the problem is as follows:

= 1.25 x 1 x 1 square foot = 1.25 square feet
