The box has a rectangular base of 5 inches wide and 33 inches long. To protect the items she will need a cover of with the same dimensions: a rectangle of 5 inches wide and 33 inches long. To find its area, we are going to use the area of a rectangle formula: [tex]A=wl[/tex]
where
[tex]A[/tex] is the are in square inches
[tex]w[/tex] is the width
[tex]l[/tex] is the length
Since we know that [tex]w=5[/tex] and [tex]l=33[/tex], lets replace those values in our formula:
[tex]A=(5)(33)[/tex]
[tex]A=165[/tex]
We can conclude that Beth will need 165 square inches of felt to protect the items in the box.
