How many sticks of butter to get to the moon?

Background Story:  State your Fermi problem in the space below.  Include your reasons for choosing this question.  This will become your  paragraph.  It needs to be the attention grabber!



how many sticks of butter does it take to reach the moon?
I chose this question because sticks of butter are easily measurable, and I figured I could easily
research the distance to the moon, and I've always wondered what the distance to the moon is, so this question was perfect for me.


2.  Ask Yourself This:  This is where you can list a minimum of three (3) questions that would provide useful ideas for further research.  Note:  if you need fewer than three questions answered, it’s probably too easy a question to qualify for Fermi.  Don’t “split up” your questions just to make more questions.  For example, if you need to know the area of a football field, ask that, not what’s its length and what’s its width.




what is the distance to the moon?
How long is a stick of butter?
how could I balance the sticks of butter to reach the moon?





3.  Helpful Hints:
a.  List the information you know or found while researching the questions listed in #2.  Some examples are the boiling point of water is 100O C or the distance from Chicago to NYC - information you can look up easily.  Include the source of any data used.
The distance to the moon is 384,403 km (238,857 miles).

include information about inches to feet to miles - if those are the measurements you’re going to use


b.  At least one piece of information used must be from your estimation and/or experimentation and/or modeling.  In other words, data you came up with.  Include the method by which you estimated/experimented along with your results.


I measured butter sticks to be 80 millimeters  (3.1 in) long and 38 millimetres (1.5 in) wide





4.  Construct a Formula:



well,  first you make unit conversions, to see what units your using, then you divide the number of kilometers to the moon by the height of a stick of butter, and you should have your answer

Conversions first, then distance to moon divided by height of butter




5.  Messy Math:  Plug in the numbers you need from the Helpful Hints or the assumptions you are making into your formula.  One of your calculations must be performed with Scientific Notation.  Check that your units cancel so you end with the correct final unit.


384,403 km/  3.1 inches = 124000.96 sticks of butter to reach the moon
redo


384 403 kilometers is
238 856.95 miles
