This original package has a big volume, and it only stores 42 rolls. We believe that we can make a more efficient package, and that we can sell it to consumers for less.
Our model/design
x 7
Since we are improving the 42 roll design, our package will have a base of 6 rolls, and will be seven rolls tall. This means the package will be 77cm tall (11 x 7) and 36cm wide at the base.

How I found the height
The formula for the area of a triangle is base x height divided by 2. So to find the area, I also needed to find the height. I decided to use the
Pythagorean theorem. All I had to do was cut the triangle in half, and subtract the square of the hypotenuse (1296cm2) by the square of half the base (324cm2). 1296 - 324 = 972cm2. The square root of 972 is 31.1769145362, so the height is roughly 31.17cm.

Measurements for the
new
42 roll package
36cm
31.1769145362cm
Volume:
43211.20342cm3

Base area:
561.18446cm2
Side area:
2772cm2

Surface area:
9438.36892cm2

Note- because capacity and volume are different, the surface area isn't necessarily the amount of materials we need for the box, but it is roughly the same.
Why Our New Innovative Way is Better
Why the Current Way is Inefficient
Volume for new design:
43211.20342cm3

Volume for old design:
66528cm3
The current way of packaging the toilet paper wastes space in between each of the toilet paper rolls and also on the sides. Its volume is 66528cm3. If you were to waste no space at all in packaging then you would have to stack each toilet paper roll on each other (Though this is an inefficient design due to the height problems). The volume would only be 52224.48cm3 which means it is wasting about 14303.52cm3 of space. Also the current way has many corners while a toilet paper roll is a cylinder so the corners are a waste of space and the more corners the more inefficient the design will be.
As you can see, the volume for the old design is much greater than the volume for this new design that we have created. In fact, out new design saves about 23316.79658cm3 of space. This is very efficient, and will make a huge impact on your business.
Ways that it can improve
The first way the package could improve is by using shrink rap, not cardboard. This would help fix the problem of empty space between corners. The company can also look toward creating different packages with a varied number of rolls. We believe that 42 and 48 aren't necessarily the best numbers when dealing with these kind of situations, and that 32 or 36 are much easier to work with.
