Question
A pyramid has a square base. Each side of the base is 9 cm. The slant height of each triangle is 14 cm. Calculate the surface area.
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:
Given ,A pyramid has a square base. Each side of the base is 9 cm.
The slant height of each triangle is 14 cm.
Therefore, surface area of given pyramid is 333 square centimeters.

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.
