... It's a 100 Gallon.

Answer 2

For a rectangular tank you calculate the volume in cubic inches and then divide by 231 because there is 231 cubic inches to a gallon. So it's about a 100 gal tank.

Answer 3

Easy one!

6 x 12" = 72 inches

Volume:

H*W*L =

72 * 18 *18 = 23328 cubic inch

1 cubic inches = 0.00432900433 US gallons

Therefore:

Your tank holds a capacity of 100.98701301024 US gallons

or:

100 US Gallons
