you fill the 3 gallon jug and pour it into the 5 gallon jug, fill the 3 gallon jug again and pour it into the 5 gallon jug again, since there is already 3 gallons in there, the 5 gallong jug can only take 2 gallons, leaving 1 gallong in the 3 gallon jug.
pour out the 5 gallon jug and pour the 1 gallon from the 3 gallon jug into the 5 gallon jug, fill the 3 gallon jug again and then add that to the 1 gallon thats in the 5 gallon jug already, giving you exactly 4 gallons. sheesh, simple quizzes and you cant even get that.

I just got one of these Brute 32 gal. and just spent the evening trying to figure this out myself, my method for water changes was filling up 5 gal. buckets with aprox. 4 gal., so I filled them up and poured them in to the trash cans. I came up with 24 gal. is around 1 3/4" lower than the inner rim. Hope this helps.

Fill it to the top thats 32 gallons-take out as many gallons as you want to be under 32. You can save the water you took out for later. Just another way to do the same thing eveyone else has already found a solution to.

I fill mine about 1" from the top & add 18 cups of salt to make the SG 1.025. I use Reef Crystals.

I do mine in a similar fashion except I dont fill it as much. When I add the powerhead and heater, it will overflow. I just tweak mine with the refractometer.

Mine has an Iwaki pump plumbed into the side. With a turn of 2 valves, it will pump the SW up a hose, into my fishroom, that can reach all my tanks.

from trash can specs (Brute 32 gallon on popular sale site):
Assembled dimension: 9.5 in. W x 10.5 in. D x 44 in. H
**that is way off. Maybe that's why people cant do math on it, but it is basic math here gentlemen. If you don't have a calculator just enter your numbers into google and it will do it for you.
Brute can by my specs:
27" high overall (with 6 inches of upper chamber height and 21 inches of the main body).
Diameter at the very top is 20".
Diameter at the (lower) top of the main body is roughly 18.75", but an average width of 18.25 if you include the bottom.
Easy way to do it is to think of it as two separate cylinders. The bottom, main body, and the top, 6 inch tall cylinder with the handles attached.
V1 + V2 = total can volume.
Volume of a cylinder is V = height * pi * (radius)^2
Vtotal = V1 + V2
V1 = 21*pi*(18.25/2)^2
V2 = 6*pi*(10)^2
So.. V1 + V2 = 7378.276 cubic inches, which is 31.94 gallons. Not bad ehh? By that, if you were to fill it to the of the main section only, leaving the 6" at the top, it would be 23.8 gallons. Then assume roughly 8/6 gallons for every inch you go up from there.
If you have measure tape please do amend this measurement for me. I opted to average it and used 18.25 to save time and because I do not have a measure tape, only a tape measure
otherwise we could do it as a cone with the top chopped off and do calculus to get the more precise volume.

How did you even find this thread, the last post in it is from 2008.

I just googled it to get a quick answer when I was doing a tank move. Like today, I googled it to get my old calculation. I could not find a quick answer.. so I tried - but forgot to leave an easy formula.
If not filled top portion, the final 6 inches of the top of the can, then
(Height of Water in inches)*(pi)*(18.25/2)^2 to get cubic inches of water, then divide by 231 for gallons
or
1 Inches = 1.13 Gallons
2 Inches = 2.26 Gallons
3 Inches = 3.40 Gallons
4 Inches = 4.53 Gallons
5 Inches = 5.66 Gallons
6 Inches = 6.79 Gallons
7 Inches = 7.92 Gallons
8 Inches = 9.05 Gallons
9 Inches = 10.19 Gallons
10 Inches = 11.32 Gallons
11 Inches = 12.45 Gallons
12 Inches = 13.58 Gallons
13 Inches = 14.71 Gallons
14 Inches = 15.85 Gallons
15 Inches = 16.98 Gallons
16 Inches = 18.11 Gallons
17 Inches = 19.24 Gallons
18 Inches = 20.37 Gallons
19 Inches = 21.50 Gallons
20 Inches = 22.64 Gallons
21 Inches = 23.77 Gallons
22 Inches = 25.13 Gallons
23 Inches = 26.49 Gallons
24 Inches = 27.85 Gallons
25 Inches = 29.21 Gallons
26 Inches = 30.57 Gallons
27 Inches = 31.93 Gallons
