from wikipedia the formula for the volme of a cylinder is:
v= pi*r^2*h
you are given d the diameter and h the height. the formula for the diamiter of a circle is 2*pi*r=d
so r = d/(2*pi)
plug and chug
I think it comes out to be about 554.4 Inch^3
this works because pi*r^2 is the cross sectional area of the cilynder. When you multiply the cross sectional area by the height you get the volume.

V = Ï r² h
V = Ï x 12² x 38 in³
V = 1742 in³ (to nearest whole number)

We would need lenghth, width and height. get your total cubic inches. 144 cubic inches in a cubic foot. 7.75 galons to a cubic foot.

i'm not sure but don't you multiply........prism or cylinder.....................V=BH so its 24x38 = 912 i think....sorry if its wrong....
