The amount of film that needs to cover the display case is its surface area

2420 square inches of film is needed to cover each display case

How to determine the amount of film needed

The dimension of the case is given as:

26 in by 15 in by 20 in

Start by calculating the surface area of the case using:

[tex]A = 2 *(lw + wh + lh)[/tex]

So, we have:

[tex]A = 2 *(26 * 15 + 26 * 20 + 15 * 20)[/tex]

Evaluate the product

[tex]A = 2420[/tex]

Hence, 2420 square inches of film is needed to cover each display case
