After I had nearly finished the Pringles I took the remaining few out so I could use them to find the volume and mass of each Pringle.
Each chip weighed 2g and finding the volume was a much more difficult procedure and with the equipment I had, it wasn't nearly as accurate as it could have been. We are all familiar with the shape of a Pringle and finding the volume of this shape would not be something that you could measure as easily as other shapes so I decided to measure the volume by displacement. This wasn't as easy as it sounded as Pringles float so this meant i would have to keep it submerged so that I could get a reading. The scale I had also wasn't that accurate and went up in 10cm^3. So I just decided to take 5cm^3 as the volume as I was getting nowhere and was running out of Pringles. Hopefully we are all familiar with the equation for density - D=Mass/Volume, so D=2g/5cm^3 which gave D to be 0.4g/cm^3. If you want it in the form of kg/m^3 then it would be 0.4kg/m^3
Now that I had the density I needed to find the volume of the pringles can which was a much easier task, just a simple area of cross section x length. The cross section was a circle which I'm sure you are all aware of so to find the area I would have to use the formula area=TTr^2, r was 3.75 so the area of the cross section was TT x 3.75^2 which equals to 44.2cm^2 and now to multiply it by the width which was 25cm would give me 1105cm^3.
To find the amount that could fit into the 1105cm^3 I would have to divide the volume of the can by the density of a Pringle which would be 1105cm^3/0.4g/cm^3 which would give me 442 Pringles which does not sound right.
Imagine if there were 442 Pringles in each can, first of all you would have the hardest time you will ever have in your life taking them out one by one and they would probably all break, and secondly, this face wouldn't be anywhere near as happy as it is right now.
