Rationale
This exploration is about the optimization of a water bottle, that is, to find out the volume of water contained in a bottle and the surface area of plastic of the bottle and try to reduce the plastic without affecting the volume. Finally, I will evolve why companies don't just use the bottle design with the most volume of water and the least amount of plastic if they are concerned with the environment and want to save themselves some money.
The reason for which I chose this topic is that I am personally very engaged with the issue of saving the planet and not polluting. My school has many water bottles lying around, and as they are plastic, they will take an average of 450 years to decompose if no-one picked them up and recycled them. It

The reason the bottles are underfilled is that they are 'first preloaded with CO2 in order to stabilise the pressure' (Gerolstiner water preduction system).
Now, I will use the same functions to calculate the lateral surface area of plastic used in these bottles using the equation SA=2π∫_a^b▒〖f(x)dx〗.
-SA1=2π∫_0^3▒〖(-0.1x^2+0.35x+2.8)dx=57.02〖cm〗^2 〗
-SA2=2π∫_3^9.5▒〖(-0.033x^2+0.423x+1.98)dx=131.45〖cm〗^2 〗
-SA3=2π∫_9.5^13▒〖(0.025x^2-0.562x+6.0875)dx=64.97〖cm〗^2 〗
-SA4=2π∫_13^19▒〖(-0.13x^2+3.97x-27)dx=107.44〖cm〗^2 〗
If we discount the dimpled shape of the bottom, it could be modeled by a circle. The radius would be f(0), so its area would be π[f(0)]^2≈24.63〖cm〗^2. Assuming that the bottom is the same thickness, the total surface area of plastic used to make each Harrogate water bottle is about 385.51cm2

In the first article "The Curse of Water Bottles" the author is obviously trying to convince people to stop wasting bottles and recycle. For example "There are solutions like using your own personal water bottle and refilling it" and that would save from buying water bottles, and reduce some of the waste. It also states "Some cities are fining homeowners and businesses for not recycling" so that means even cities are trying to get people to stop wasting water bottles. Companies and/or states have tried putting rewards on the bottles if you return them, as stated "Some states have tried to put a nickel return fee on water bottles like those on soda and other beverages" but it still doesn't work out for everyone, because "grocery

...er than the bottled water available for purchase. Also the amount of energy wasted in producing the plastic bottles is not necessary because water is available from every tap in most households.
In today’s society it is uncommon to see people walking around without water. Those who carry water with them either have their water in a reusable bottle or have bought bottled water. Bottled water is the more commonly found type of water carried around, reason being that it is easy to just buy a huge pack so that a person can just grab a bottle a go. The problem with bottled water is that more often than not, the bottle does not get recycled, but instead gets thrown into the garbage. The problem with this is that the bottles end up in a landfill. However, in this past year alone American’s used “about 50 billion plastic water bottles” (Ban The Bottle, n.d., Para. 4). Most people do not see the big difference between bottled water and tap
The formula that needs to be used to get the volume of a box is:
For ever water bottle made, non-renewable resources are wasted to produce an unnecessary luxury. For the bottled water Americans enjoy, seventeen million barrels of oil are used (excluding transportation), which could fuel more than 1.3 million cars for a year. Most water is imported and exported from places that are thousands of miles away, like Fiji. Although oil is controversial in nature, for every one liter of water produced, three liters are used; the excess water wasted can supply clean water to the world’s poorest countries. Moreover, the energy used in bottle production can supply energy to over 190,000 homes. The resources that can be replaced by ceasing the production of water bottles can solve many global problems faced by a growing population.
According to the “Competition in the Bottled Water Industry in 2006 Case,” bottled water industry became the one of the world’s most attractive beverage categories, as more and more people began to focus on health and fitness. Consumers start realizing the need of proper hydration, and they began purchasing bottled water instead of drinking tap water, because they were worried about safety of tap water, which tasted like chemicals. Actually, tap water contained chemicals, such as chlorine and fluoride, which are harmful for human body; however, this problem was solved when the bottled water was brought to the market. Due to bottled water’s convenience, purity, and portability, and safety, bottled water industry began to rise rapidly. During
Total surface area of cone (A) = lateral surface area of cone + area of base. Lateral surface area (L.S.A) = r s square unit. Substitute the r and s value in formula and simplify.
Promote social responsibility; recycle scrap water bottles and use recycled plastic in the production of our bottles
The second part of measuring for volume, we measured the density of Isopropyl alcohol the same way we did for the water. We measured the mass of the empty graduated cylinder which was 46.35 grams and then added 25.0 milliliters of Isopropyl alcohol to it which made the mass 66.95 grams, causing the difference to be 20.6 grams of the Isopropyl. This was 4.4 grams less than what it should have measured out to be.
From a business point of view, it seems so ignorantly deceptive, yet it is absolutely genius. With a little marketing, bottled water has become a huge success. However, it is killing the environment and the water is usually comparable to tap water regardless. The “The Story of Bottled Water” is a very well-made short film that takes viewers into the dark world of manufactured demand.
Being convenient enough for everyday use and even tasting better to some, plastic bottles are a popular way of consuming beverages. They are convenient and to some people, can even taste better. However, the process of manufacturing and transporting the millions of bottles produced is detrimental to the environment. Continued use of plastic bottles could exponentially hurt the planet.
example to bottle eight gallons of a beverage would take only two pounds of plastic but
