Areas of Polyhedra  
Polyhedra  
The surface area of a right prism whose base is a regular polygon. 

For a
regular polygon, the area of the base is calculated by multiplying its
perimeter by its apothem and dividing it by 2. The lateral
area of this prism forms a rectangle, its surface area is calculated by
multiplying the perimeter of the base by the height of the prism. 

You can
rotate the figure by moving the red dot. What you are going to measure
