For the past few weeks KFC had being aiming to design, and price, a water and grain storage facility for a village that has fifty families. The storage facility must be able to contain a two week supply of water and grain. The storage facility must be able to contain a two week supply of water and grain. The walls and roof of the facility will be made out of metal sheet that costs $14 per m2. The walls and roof of the facility will be made out of metal sheet that costs $14 per m2. The facility must be placed on a 20cm thick concrete floor. The concrete costs $640 per m3. The facility must be placed on a 20cm thick concrete floor. The concrete costs $640 per m3. We must make every effort to keep the cost as low as possible. We must make every effort to keep the cost as low as possible.

3. How many people’s in a family? Research had shown that the average population of a family is around 4 ± 1(two adults and two children) Research had shown that the average population of a family is around 4 ± 1(two adults and two children) Therefore 50x4 ±1=200±50 people are included in this 50 families Therefore 50x4 ±1=200±50 people are included in this 50 families
