It looks like you are talking about rectangular-prism tanks. I ams sure you know how to compute the volume of that geometrical shape.

V = L * W * H

Subtract the volume of the smaller tank from the volume of the larger tank and you will have the answer, in cubic inches, if W, L and H are in inches.
