3x the Chocolate?
What a great Calculus activity (hint: rotational volumes).
Cross sections with an exacto:

Pretty good fit.
Here’s the data for each type. I used a caliper to measure the dimensions.
To account for the candy shell you can measure pixels in an image manipulation program. If you’d like to follow along at home, the M&M Mega has a thickness of 404 pixels, and the chocolate only (no shell) has a thickness of 333 pixels. The regular M&M has a thickness of 251 pixels, and a chocolate thickness of 210 pixels.
You have enough information to do some damage, go ahead and see if the M&M’s Mega truly have 3x the chocolate of the regular M&M’s.
Fun. Great activity for calculus.
Phew, no fox news.
