Its a long explanation how but it should be about 25 gallons
No it is not.
Really no one fish tank is the biggest.
flat head (fish)
fish
4 * 3 * 3.14 = Fish
About 29 gallons
A bit less than 75 US gallons.
It depends on the length of each side and the height of the tank.
No. Goldfish grow very large and are messy. Fancy goldfish need 20 gallons of water per fish plus 10 gallons for each additional fish (so 50 gallons at minimum for 4). Common and single tail goldfish need 30 gallons each plus 20 gallons for each additional fish
Making the assumptions that these measurements are in inches, and that the fish tank is a perfect cuboid, the volume of the fish tank is 49 x 19 x 21 = 19,511 cubic inches.Rounded to two decimal places, this is equal to 70.47 gallons.
To find the volume of the fish tank in cubic inches, multiply the dimensions: 20 x 18 x 21 = 7560 cubic inches. To convert cubic inches to gallons, divide by 231 (since 1 gallon = 231 cubic inches). Therefore, a fish tank measuring 20 x 18 x 21 inches would hold approximately 32.8 gallons.
A U.S. gallon is exactly 231 cubic inches. 60 x 18.75 x 19 = 21,375.0 cubic inches = 92.532 U.S. gallons
1 goldfish. It may seem tiny now, but they grow up to be around 6 inches. Add 10 gallons for each additional goldfish. Example: 20 gallons + 2 more goldfish (10 gallons) = 40 gallons and 3 goldfish total.
A good rule of thumb for fish placement is to try and equal inches of fish to gallons of water.
231 cubic inches = 1 gallonVolume = (length) x (width) x (depth) = (48 x 19 x 11) = 10,032 cubic inches = 43.429 gallons
231 cubic inches = 1 gallon.36" x 12" x 24" = 10,368 cubic inches = 44.88 gallons(rounded)
5 gallons for each fish. ex: i have two so i would need 10 gallons
