What you are asking for is the volume of a torus, which is quite a complicated problem.

What grade level would this be?

If you want an approximation ....

Assume we cut the tube and stretch it into a long cylinder.

The the volume would be π(1^2)(82 = 82π

or appr. 578 cubic inches.

Is this answer sufficient?
