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
