The rule of thumb is 1 gallon per 1 inch of fish. But of course if you have bigger goldfish you will need more room. So for larger fish, go 1 gallon per 3 inches of fish.
two to three

3.75 gallons 1 Gallon = 8 pints 1 pint = 0.12 gallon
The gallon (volume) and the inch (length) can not be equated.
About 6 and 3/4 gallons in a 30 liter tank (4.5 liters to a gallon).
30
For twenty small (1-1.5 inch) Goldfish you should have something like a 30 gallon aquarium.
You cant. Goldfish need much bigger tanks. 20-30 gallons. I bought 2 goldfish when I was new to aquarium hobby and put them in a 5 Gallon tank. The first one died in just one and a half day. The other one died just hours after the first one :( So if I were you, I would get a bigger tank.
Regardless of the type or size of goldfish the minimum acceptable size of an aquarium for a goldfish is 30 gallons. Buy a tank that is at least 30 gallons if you plan to have goldfish. You can comfortably fit 3 goldfish in a tank this size but no goldfish in a tank any smaller. Goldfish are essentially pond fish and need lots of space to swim; they will not thrive in a small aquarium.
Its all your choice, my friend. However, the bigger the aquarium, the better the ecosystem- so I'd go with the 40 gallon. I have a 40 gallon fishtank myself.
One goldfish needs a 30-gallon tank, and an additional ten-gallons per additional goldfish. Goldfish can grow to be 10-12-inches long.
No, one goldfish needs 20 gallons alone at minimum, plus an additional 10 gallons for every goldfish you wish to add. This means that for two goldfish, you need at least a 30 gallon aquarium.
7....But you should keep an good watch on them.
Goldfish need plenty of room to swim around and get very large. In a 1000 gallon pond you could put 25-50 goldfish just keep in mind that goldfish grow very large and need about 20-30 gallons each when full grown.
The rule of thumb for stocking levels in a freshwater aquarium is 1 inch of fish per gallon of aquarium. For instance, five 1" guppies in a 5 gallon tank, or ten 3 inch cichlids in a 30 gallon aquarium.
A 30 gallon would be suitable if done properly for a tank up to about 125 gallons. Maybe 150.
Goldfish release growth-inhibiting hormones into the water they live in: the more goldfish in a smaller space, the less likely they are to grow. For instance, if I have a common goldfish in a 5 gallon tank, it will grow to about the same size if I had 6 of the same fish in a 30 gallon tank. But leave that fish alone in a 30 gallon tank, and it will grow larger. This is why pond goldfish grow bigger. But goldfish won't grow at all in seawater; they aren't saltwater fish.
