  2. Our Process • Research • Consolidation • Answers

  3. How many people in a family? • 2.61 children born/woman (CIA World Factbook) • Round down to 2 children • Add 2 parents • Equals 4 people in a family!

  4. Water

  5. Starting Questions • How much water does each person use? • What do we use water for? • What is the best shape to store water in?

  6. Answering Questions • What do we use water for? • Drinking • Bathing • Washing (dishes, laundry) • Toilets • Cooking

  7. Answering Questions • How much water does an average person use? • Internet research • http://www.newsobserver.com/weather/drought/story/1016009.html • 69.3 gallons per person for indoor purposes • laundry, shower, toilets, cooking, drinking • Convert into litres • 1 gallon = 3.78541178 litres 69.3 gallons ≈263 litres • Leeway: 263 ± 2 litres

  8. Answering Questions • What 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

  9. Calculation • Total amount of water needed for entire village: • 265L × 4 people × 50 families × 14 days = 742 000L • Volume 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

  10. Surface Area of Tank

  11. Justification • Viability 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 water • Level of Accuracy (nearest whole number): • Easier to see the difference between figures

  12. Our Storage Tank • Has a capacity of 742 000L • Is in the shape of a cylinder • Dimensions: • Radius: 4 metres • Height: 15 metres

  13. Grain

  14. Starting Questions • What 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?

  15. Answering Questions • What kind of grain are we storing? • Grain can be used to make many types of food • Rice, corn, oats, rye • Bread • for our purposes, we’ll pretend that we’re storing rice

  16. Answering Questions • How 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

  17. Answering Questions • What kind of shape is best for storing the grain? • Real life examples • Cylinder has the largest area for a fixed perimeter • Cylinders are also used for silos

  18. Examples of Grain Storage http://www.mawaterquality.org/gallery/photos/hog%20grain%20storage.jpg http://www.dengie-crops.com/media/silos%20and%20lorry.JPG

  19. Calculation • 100cm3 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

  20. *this is where a table will go*

  21. This is where our answer will go

  22. 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.
