CJDev's+Storage+Facilities

The task is 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 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. Keep the cost as low as possible. In all your calculations consider an appropriate degree of accuracy.

To Do:
 * **Final** numbers for grain/water use per person/in total
 * Do the math
 * Split the presentation

The one that Cara did again: THE FINAL ONE!!!!! (well, except... two slides? i'm sharing responsibility): you just have to change the cell next to the one that says "m^3=" to change the volume.... not that you need to. um, supplementary material, i guess! we have to edit this, yeah? and find our answer for the grain thing!
 * can someone please do the final calculations for the grain storage thingie according to my example with the water storage? the excel sheet that i used is below:**

THE FINAL FINAL REAL ONE (unless someone else makes any changes): check your e-mails for who's reading which slide!
