1 gallon = 231 cubic inches Assuming the dimensions in the question represent inches: (17 in x 11 in x 12 in) = 2,244 cubic inches = (2,244 / 231) = 9.7143 gallons (rounded), right up to the top.
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.
You actually have a 20 gallon tank. There are 231 cubic inches in a gallon. So if you take your length times your with you get: 24x12 = 288in square. Then multiply that times the 16 inches of height and you get 4,608 inches cubed. Divide that number by the 231 cubic inches per gallon and you get: 4608 (inches cubed)/ 231(cubic inches per gallon)=19.94 Gallons or a 20 gallon tank.
