Answer 1

The 14" could be the measurement from the tail to the mouth. I suspect the part that receives the water is the bottom half of a 7.5" diameter sphere-like volume.

Volume of a sphere = (4/3)*pi*R^3

(4/3)*pi*(3.75 cubed) = 221 cubic inches.

The water appears to occupy the bottom half
approximately 110 cubic inches.
close to
0.478 US gallon
0.4 Imperial gallons

Answer 2

Eolian is on the right path. However, I think that 14" includes the tail which holds no water. And the bowl is spheroid, not a rectangular cube. Even more difficult is that the spheroid cannot be filled because the opening is off to the side, not straight up.

We would need the dimensions of the bowl itself to find the volume of a sphere (it's close to a sphere), and know at what height the opening starts to subtract the amount of volume above that to give how many gallons it holds.

Answer 3

Looks like 1.7 gallons to me, could be less since you can only half fill it before water pours out the mouth. I'd guess in the picture it has about 1 gallon in it.

I think the dimensions given are for the whole thing not just the water filled part.

Answer 4

The dimensions of the shape are:

V = lwh = (14)*(9)*(15/2) {15/2 = 7-1/2}

V = 945 cubic inches

Now, there are 231 cubic inches in a Gallon, so we have to convert the measurement:

(cubic inches)*{gallons/(cubic inches)} = gallons

So, let's do it:

(945 cubic inches)*{1 gallon/(231 cubic inches)}

= 945 gallons/231

= 4.09 gallons

Answer 5

The figure Eolian provided looks correct for those numbers, but as they show it you are probably only filling it 2/3 of the way.

Answer 6

A little over a gallon in the fish bowl.
