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.

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 ft ^{2} ^{)} .
If you have two cells in that table, the space they occupy is 2 square feet (2
ft^{2} ).

= 2 square feet (2 ft ^{2} )

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?

What if your wall were 8 feet high
and 12 feet wide? How many square feet of wallpaper would you need?
