How can i find out how many gallons/litres are in square pots? I looked at the pots and they dont say. They are 5.5" x 7".

How to find gallons in square pots?

Umm... 2nd or 3rd grade algebra? Perhaps you should tape up the holes and fill the pot with water and then measure the amount of water to find out how much the pot holds. Obviously you don't have much truck with math...
You take the width, times height, times length, and you get cubic inches as an answer.
269 cubic inches is one gallon of dry material. (wet gallon is different)
5.5 x 7 x ? = how many cubic inches your pot has. (you didnt tell us the other measure)

5.5" SQUARE,
hence square pots
5.5 x5.5 x7= 211.75 in³
1 cubic inches = 0.00432900433 US gallons
211.75 in³ = 0.916666 gal
ftr, i didnt know how to do this.
but 10 secs of time and google got me the answer.
so easy a retard could do it

Not so easy guys...
Square pots are essentially capped pyramids; not cubes or rectangular prisms.
The volume of a capped pyramid is:
V=h/3*(G+sqrt(G*g)+g)
V = Volume
h = Height
G = Area of Base 1
g = Area of Base 2
sqrt() = Square root function
Can you tell me the length of the pot's small base's side? For now I'll just assume it's 4.5" or so (I'm pretty sure it is).
Let's fill in the values:
V = 7/3*(5.5^2+sqrt(5.5^2*4.5^2)+4.5^2)
V = 175.583333333 in^3 = 2.87729532067 Liter = 0.760101010101 US Gallon ≈ 3/4 of a US Gallon
Now multiply 3/4 US Gal with the number of pots you want to utilize, and you'll get the (near) exact amount of medium you need... Example:
You need 20 pots; 20 * 3/4 US Gal = 15 US Gal minimum needed to fill those pots.

A close approximation for the stoned grower without a calculator:
V=h*[(A+B)/2]^2
where A is the width of the pot at the top and B at the bottom and h is height, so: V=7*(4,5+5,5)/2)^2=7*25=175 in^3
Not so easy guys...

Thanks bro, thats why i asked, b/c the pots are pyramid shaped and im horrible at math. Everyones like..."thats so easy" and "even frank can do it". Well i bet before pontiac posted, none of you knew how to figure this out mathematically, only physically. So screw off. Im done posting here already as pontiac has asnwered my question. K+ to you dude. thx s'h
....please

3.8 liters = 3 g just back into it
A "dry" gallon of soil is one cubic foot. That pot holds about one half dry gallon. In liquid measurement it is more like 1 gal.
dam it maybe i guess i'll have to use my brain i spose ?.HH. =]-~
A dry gallon is 269 cubic inches in volume.
Do the math on 1 cubic foot...
12" x 12" = 144
144 x 12" = 1728 cubic inches (that is 6.42 gallons)

Square pots are usually listed by their capacity in litres, 1 litre is 2.2 pints so a gallon is 3.5 litres.
The standard square pot sizes in Europe are 3.5 litres, 6.5 litres and 11 litres, which is roughly 1, 2 and 3 gallons.
Why oh why does the US stick with an archaic obsolete system of measurements when the rest of the world is metric?

Well, there are over a billion people on this Earth who prefer not to use a phonetic alphabet. Tradition is a powerful thing and very hard to change...
The US is far from the only place that hasn't gone metric. All systems have their advantages and disadvantages. If we used a duodecimal numeral system then feet would be more convenient than meters. So at least we all count to ten and start over, it'd be pretty f*cked up if the US would count: one, two, three, four, five, six, seven, eight, nine, twelve, twelweteen, thwirteen, fourtween etc to go with feet and inches
Some cultures do/have, btw
Ever hear of a unit converter bro?
Oh and last I remember, they sent men to the moon using some of those "archaic and obsolete" systems of measurements; a feat the rest of the world has yet to accomplish.
Just cus you feel something is inferior doesn't make it so.
excuse me.
