    No, it’s 20 (2 times the square root of the sum of 6 squared and 8 squared).

    You're saying - two at each end. The diameter is going to be effected by the inside walls, floor and ceiling that touch the doors.

    2 doors, 8 ft. what separates the doors into two? Then say, there's two feet on either side of the doors, now we have twelve ft. by 40?

    OR - is there ONE door at each end adding up to two?
    Make everything from toy guns that spark, to flesh-colored Christs that glow in the dark. It’s easy to see without looking too far, that not much is really sacred.

    No, he means openings like the ends of a paper towel roll. You need to calculate the circumference and multiply by the length to get the square footage of the metal required to make the cylinder.

    Okay, thanks. His description seemed odd.
