How many gallons of waterare in a area 30 inches long by 12 inches wide by 18 inches deep?

Answer 1

It's a 29 Gallon tank. You can figure out gallons from cube inches here: http://www.metric-conversions.org/volume/cubic-inches-to-us-liquid-gallons.htm or you can see a tank with same measurements here: http://www.myfishtank.com/ProductDetails.aspx?productID=7#

Answer 2

The volume of that space is 30" x 12" x 18" = 6,480 cubic inches = 28.052 gallons.

There's no way I can tell how much water might be in it.

Answer 3

There are 231 cubic inches in a gallon of water, so 48x18x7=6048 cubic inches, and 6048/231= approximately 26.2 gallons.

Answer 4

48in x 19in x 11.5in = 10,488in3

1 US gallon = exactly 231in3.

10,488in3 x (1gal/231in3) = 45.403 US gallons (rounded to three decimal places)
