How many gallons?

[jesstanner]

Do you guys know how many gallons are in the 10 inch bulb bowls from Michaels? How about the 12 inch? The 10 inch look like 1.5ish to me but I'm hoping it's 2! Thanks

I usually figure out cubic inches and then put it into google's calculator (__ cubic inches to gallons). I don't remember how to figure out cubic inches for a round shape at all, it's been a long time since I've taken a math class, lol

you can get very large 2 gallonish glass vases at michaels over in the glassware area
