The surface area of a box, which is a cuboid, depends on its length, width and height. A cube is a special type of cuboid in which the length , width and height are all the same.
Because juice boxes come in all shapes and sizes, you would need to know the measurements of each side to calculate the surface area. The formula to do this is: 2(lw+lh+wh) unless the juice box is a shape other than a rectangular prism.
I guess it depends on the kind of shoe box. Let's take a regular shoe box with six rectangular sides. Let the dimensions be a x b x c The surface area is 2(ab + ac + bc) Intuitively, you have three different dimensions, a, b, and c. So each panel has area of ab, ac, or bc. Then if you look at opposite sides of the box, you see two opposite sides are the same, so you multiply the sum by two.
The formula will depend on what it is that you are trying to find: the volume or the surface area.
you multiply the length times width times height.
Multiply length x width.
To calculate the area of the front surface of a box, you would multiply the width of the box by the height of the box. This calculation gives you the area of the rectangular front surface.
2 x ((L x W) + (L x H) + (H x W))
The good thing about the developments of rectangular boxes is that they are still rectangular! In order to find the surface area of the paper needed to make a box, you would first need to determine the measurements of your finished box. One you have determined your length (L), width (W), and height (H), you will need to do some simple math. 2(LxW) + 2(WxH) + 2(LxH) = the area of paper that you need to make a box.
With the developments of rectangular box on paper how am I supposed to find the area of the paper that I need to make the box -- Not find the air of the box itself but the paper used? By measuring the area of one side of the box and multiplying by the six sides. You get the total area of the box (Cube).
The answer will depend on the shape (and size) of the box: some have a rectangular cross-section, others circular.
measure the sides of the box
It should be relatively easy to find the surface area of a box when you are given the surface area.
