m+m maths 1: find the volume using m+ms!

Are you bored by doing volume calculations?

Are you looking for a new and exciting way to calculate the volume of, well, things maths teachers ask you to calculate the volume of? Like what? You know, cubes or cylinders or cones or stuff. Well, today mathspiggies, we have the perfect solution for you. Yes!

We will calculate volume by counting m&ms!!!!  Do I hear any complaints???? Anyone!!! Right!

WARNING: You may need a ship load of m&ms!!! Just saying.

Mathspig salutes CWanamaker for doing maths over and above the call of duty by actually measuring how many m&ms fit in various containers. He has provided us with the RPR (RAndom Packing Ratio) for m&ms(below) and you will find his experiments here.

Two things you may need to know:

   1 fl ounce (US) = 29.6 ml

              1cm³  = 1 ml 

If you are like me, mathspiggies, you will be amaaaazed how many m&ms it takes to fill, say, a coffee mug. Nevertheless, you can calculate the volume from the no. of m&ms and you will find the answers here:m&m maths answers

 

m+m maths 2: Guess, NO, calculate the number of m+ms in a jar!

Of course, mathspiggies, we can do the reverse maths and cheat … and use our superior maths skills to calculate the no. of m&ms in a cookie jar and then you WIN the cookie jar full of m&ms at the school fair.

HOW MANY BAD HAIR DAYS in your life?

According to The Manchester Confidential a consumer survey found that the average British female will endure 7,332 bad hair days in a lifetime!!!!

How many years is that? Do the maths.

7,332/365 = 20.09 years 

0.09 x 365 = 32.85 = 33 days

O MY GOODNESS, 20 years and 33 days of BAD HAIR. 

Makes you wanna go back to bed or shave your head.

Hoo Roo
