  2. a prism has 3 pairs of rectangular faces, so if its dimensions are x,y,z then its area is 2(xy + xz + yz)

    a cube is just a prism, where x,y,z are the same

    a cylinder is just like a prism, except round.
    Just as a prism's area is its base perimeter times its height, plus the two bases,
    a cylinder's area is 2πrh + 2πr^2
