A Real Steal for Cereal

Even a big box of cereal weighs hardly anything. It can fill a lot of bowls, but it’s so light you can throw it across the kitchen (not that you should). Even lighter are those mini boxes of cereal that hold just 1 serving. So our fan Henry S. asked, how many mini boxes fit inside a big cereal box? This turns out to be a great question, because those mini boxes cost a LOT more money for each bite. A big box holds 12-14 ounces, while the mini boxes hold almost exactly 1 ounce. A big box costs around \$3 or \$4 — but so does the 8-pack of minis at Walmart. On the other hand, those combo packs give you lots of flavors to try, and that excitement might be worth it.

Wee ones: How many “faces” (flat sides) does a cereal box have? Or count them on a shoebox or other rectangular box!

Little kids: If a combo pack has 2 mini boxes of rice Chex, 2 wheat Chex, and 2 cinnamon Chex, how many boxes does it have in total?  Bonus: If you eat a rice Chex on Tuesday, then wheat on Wednesday, then cinnamon the next day, then start over with rice, on what day do you eat the 2nd cinnamon Chex?

Big kids: Kellogg’s 30-pack of minis has 8 different cereals. If the boxes are divided among the flavors as equally as possible, for how many flavors do you get an extra box?  Bonus: If that 30-pack costs \$21, how many ounces of cereal could you get if you instead bought a bunch of \$3 12-ounce boxes?

The sky’s the limit: If you have 10 mini boxes in 2 rows of 5, and that includes 2 boxes of Apple Jacks somewhere, how many different ways can those 2 boxes of Apple Jacks be placed?
