If a regular n prism has 22 faces, and the sum of the lengths of all sides is 100cm, and the side length of the bottom is 5cm, what is the area of one side of the prism?

If a regular n prism has 22 faces, and the sum of the lengths of all sides is 100cm, and the side length of the bottom is 5cm, what is the area of one side of the prism?

Except that the two bottom surfaces are regular 20 prisms. Edge length = 100 / 20 = 5. Area of one side = 5 * 5 = 25
