How Many Cheerios in a Box?

How Many Cheerios in a Box?

January 7, 2019

Our fan Arun W. just asked us a question we’d never thought about: how many Cheerios are in a box of Cheerios? After all, you want to know how many Os are going into your tummy. Cheerios were invented in 1941 by food scientist Lester Borchardt. He spent months trying new ways to puff up oats, and came up with the O. As for how many Cheerios in a box, luckily we have some handy here at Bedtime Math (well, they’re Multi-Grain Cheerios, but same idea). Here’s exactly 1 cup of them…can you guess how many are in there?…There are 252! So a 12-ounce box holds 11 cups, giving us 2,772 Cheerios in the box — and lots of crunchy puffiness.

Wee ones: What shape is a Cheerio?

Little kids: If your spoon holds 2 oat Cheerios, 2 wheat and 2 rice, how many multigrain Cheerios do you have?  Bonus: If you’re counting up 60 Cheerios by 10s, what numbers do you say?

Big kids: If we say there are about 250 Cheerios per cup, how many cups do you need to get to 1,000 Cheerios?  Bonus: If you love, love, love Cheerios and eat 20 cups of them, how many little Os is that? Use your answer from the last question to help!

 

 

 

 

 

 

 

 

 

 

 

Answers:
Wee ones: A circle…from above it looks like an “annulus” (a ring), and in 3D it’s a “torus” (donut shape).

Little kids: 6 Cheerios.  Bonus: 10, 20, 30, 40, 50, 60.

Big kids: 4 cups.  Bonus: 5,000 Os, since you have 5 sets of 4 cups, and a set of 4 cups has 1,000.
