Based on how little cereal comes in boxes these days I’d be surprised if it filled one barrel.

Cereal was almost empty last night. Only two or three drums !

No bread or milk; there is a snowstorm in North Carolina.

Can I use a funnel?
Asking because if when I fill my bowl in the morning, half of the cereal lands on my worktop.

Seven.

prove me wrong.

Two. (Compacted.)

18 boxes of Honeynut Oats would fill one drum, so a fully stocked shelf would fill about a dozen drums

If you use a compactor to remove all the air then the cereal would likely fill ½ a 55 gallon drum.

Here’s the guy who can probably tell you: Rob Cockerham, hero of “How Much Is Inside?”

Be sure to scroll down and check out some of the contents he has measured. For example, how large an area can you cover with one tube of lipstick? Aren’t you dying to know?

Sounds like math homework. You would multiply the length x height x depth of the aisles to get volume, then put in a fill factor for air gap over the boxes and empty space due to product shortages. That gets you volume of cereal. Convert to gallons and divide by 55.

At the Safeway I go to, they could put maybe 8×55 gal barrels in that space. If the fill factor is 0.5 then 4x barrels would be filled.

Right, that’s one waym @RocketGuy but if I were trying to save space, I would take the cereal OUT of the box and dump it in the drum, and then fold the cardboard flat, to save space.

Moisture and oxygen would make it all stale after a while unless you found a way to get at the cereal without allowing that to get in.

@RocketGuy You seal it up with a desiccant cannister and an activated hot hands pack or bag of iron powder.

and a drawer/air lock dispenser like the ones for cereal bins in cafeterias.

@RocketGuy I like that idea.
