Good work. Now let's go a step farther.

Imagine that you want to cover your kitchen wall with new wallpaper. Imagine creating a table against that wall. Each column will be one foot wide and each row will be one foot wide. If your wall holds 6 columns and 8 rows, how many cells will you have? 

--> cells. Check My Answer 48 cells

Each cell in that wall table will be 1 foot wide and 1 foot high. It is square. The space held  inside of each cell is said to be 1 square foot (1 ft²⁾. If you have two cells in that table, the space they occupy is 2 square feet (2 ft²).

= 2 square feet (2 ft²)

If you have a table that has 48 squares (6 one-foot columns X 8 one-foot rows), just like the table against our kitchen wall, how many square feet would the table or the wall cover? Check My Answer 48 square feet

Good. So, if you want to buy wallpaper for that wall, how much would you buy?
