Answering QuestionsHow much water does an average person use?
Internet researchhttp://www.newsobserver.com/weather/drought/
story/1016009.html69.3 gallons per person for indoor purposes
laundry, shower, toilets, cooking, drinkingConvert into litres1 gallon = 3.78541178 litres
69.3 gallons ≈ 263 litres Leeway: 263 ± 2 litres

Answering QuestionsWhat is the best
shape to store water in?
Perimeter and Circumference vs. Area (of 2-D objects)
Circle vs. Square Real life examples A cylinder is the best
shape to store water in

CalculationTotal amount of water needed for entire
village:265L × 4 people × 50 families × 14 days = 742
000LVolume of storage tank: 742 000L of water =
742 m3
This estimation has more water capacity than is necessary because there is an extra 2 litres for every person

JustificationViability vs. Cost
Is it really that good to have a 26m structure?
Is it possible to have a 26m structure that will hold its weight?
Amount of water used:Leeway for water use of people in case they
need more waterLevel of Accuracy (nearest whole number):
Easier to see the difference between figures

Starting QuestionsWhat kind of grain are we storing?How much grain are we putting in storage?What kind of shape is the best for storing the
grain?

Answering QuestionsWhat kind of grain are we storing?
Grain can be used to make many types of foodRice, corn, oats, ryeBread
for our purposes, we’ll pretend that we’re storing rice
![Page 16: Storage Facilities](https://reader036.vdocuments.us/reader036/viewer/2022062517/5681378f550346895d9f2e30/html5/thumbnails/16.jpg)
Answering QuestionsHow much grain are we putting in storage?
The space that the cooked rice takes up is 3-4 times the space that uncooked rice takes up
Each person eats about 300cm3 of cooked rice per meal
300cm3 of cooked rice ≈ 100cm2 of uncooked rice
![Page 17: Storage Facilities](https://reader036.vdocuments.us/reader036/viewer/2022062517/5681378f550346895d9f2e30/html5/thumbnails/17.jpg)
Answering QuestionsWhat kind of shape is best for storing the
grain?Real life examplesCylinder has the largest area for a fixed
perimeterCylinders are also used for silos

Calculation100cm3 uncooked rice × 3 meals × 4 people ×
50 families × 14 days = 840 000 cm3 of uncooked rice
840 000cm3 = 0.84m3
Shed has to have a volume of 0.84m3

Justification‘cause like, it just is, man.(:-.- no, not really. This is where we write a
justification that is not yet thought of. I mean, we have to think about it.
