A regular n prism has 12 sides, and the sum of all sides is 100cm, and the side length of the bottom is 5cm

A regular n prism has 12 sides, and the sum of all sides is 100cm, and the side length of the bottom is 5cm

A regular n-prism has 12 faces, 10 sides without the upper and lower bottom faces
So, this is a regular 10 prism
Its lateral edge length = 100 / 10 = 10 cm
The sum of its side areas
=(5*10)*10
=50*10
=500 square centimeters
