Question
A square pyramid is covered with decorative wrapping paper with no overlap. The net of the box is shown on the right. How many square centimeters of wrapping paper are needed to cover the surfaces of the box?
Hint:
The surface area of Pyramid = 
where p is the perimeter of the base , B is area of the base and l is the slant height of the pyramid.
The correct answer is:
This net forms a pyramid with base as it has a square base and 4 triangles as the side surfaces. 
Therefore,180 square centimeters of wrapping paper are needed to cover the surfaces of the box.

Identify the shape that will be angled cross-section of a rectangular pyramid.
The plane cuts the pyramid at an angle which is not parallel to the base of the cone, this is the reason why we are getting a rectangle but with a length : breadth ratio different than that of the base.

Name the shape that would result from slicing a rectangular pyramid parallel to the base
Since the pyramid is rectangular, this means that the base of the pyramid is a rectangle. Therefore, if we slice it parallel to the base, we’ll get a cross section which will look like the base of the pyramid, i.e., a rectangle.
