How much cereal is inside one of those boxes of Cheerios?
Inspired by Leif's Fruit Loop Necklace, which I bought a regular size (15oz.) box of Cheerios, and set about counting them.
Before I opened the box, I took a quick poll of the people present. How many Cheerios would be in here? I guessed 890, Mike guessed 734, Ken guessed 662 and Antonia guessed 1200.
How about you?
Cheerios.
I used wooden clothes pins to keep track of 50s and 100s of Cheerios.
The final count was finally in: Four thousand, eight hundred and two Cheerios were in the box.
I was surprised to find that most of the cheerios were complete circles, with less than 40 little broken bits (oddios).
Only one hundred Cheerios took up 18 5/8 inches of string.
The next day after work, Jane, Brianna and Mike helped me hoist the entire Cheerios string outside to measure it. The string was half a block long. It was so long that I had to move the tape 3 times to measure the whole string. It ended up being 73 feet, 2 5/8" long.
At last, a Cheerios necklace suitable for Mr. T!

The recommended serving size is about one cup of Cheerios. That is about 5 feet worth, so if you eat your height in Cheerios, you are getting 50% of your RDA of Folic Acid.
Steve Pham hated Cheerios because they never give out toy prizes.
