You can look at your tank as composed of two boxes = (actually=20 one and 1/2 boxes).  1st box is  3.75" x 6" x 15" =3D 337.5 = cubic=20 inches.
 
A second box is 3.75 " x (11-6)" x 15" =3D 281.25 = Cubic inches=20 but you really only have 1/2 of this box,   so triangular section = volume  =3D 1/2 (rectangular section) volume  =3D = 281.25 * 1/2 =3D=20 140.625 cubic inches
 
So total volume =3D volume of 1st box (337.5 )+ = 1/2 volume of=20 second box (140.625) =3D 478.125 cubic inches or 2.07 US = Gallons

What wall thickness Wendell? .010 thick NO! 1 inch (wall) = yes. Give=20 us an idea of what you are using it for.
