### Finding the Dimensions of a Box

You want to construct a cardboard box from a cardboard strip that is
8 inches wide. The dimensions of the box are 8 inches by 8 inches by
4 inches. How long does the strip need to be?

I tried to find the answer by saying 8x8+4+4 and I got 40, but none of
my friends or family can help me and I'm not sure if I'm right.

Hi Kaila,

Get out a cereal box, and note that it has three pairs of sides,

two sides with dimensions length * width

two sides with dimensions length * height

two sides with dimensions width * height

In your case, length = 8, width = 8, and height = 4.  So we can draw
those sides:

+---------+
|   8     |
|        8|  length * width
|         |
|         |
+---------+

+---------+
|   8     |
|        8|  length * width
|         |
|         |
+---------+

+---------+
|   8     |
|        4|  length * height
+---------+

+---------+
|   8     |
|        4|  length * height
+---------+

+---------+
|   8     |
|        4|  width * height
+---------+

+---------+
|   8     |
|        4|  width * height
+---------+

If you put all the sides together, you can make a strip of cardboard 8
inches wide... and how long?
