Unopened three-dimensional shapes reveal many hidden secrets that can be used for different calculations. Let's come to the unfolding part, which is one the most demanding part. The height of a truncated pyramid is the perpendicular distance between the bases and the apothem is the height of any of its sides. The lateral faces of a truncated pyramid are trapezoids. This one is special and mathematicians gave it a beautiful name which is, "truncated pyramid". A truncated pyramid is the result of cutting a pyramid by a plane parallel to the base and separating the part containing the apex. Yes, it will be called a pyramid but this isn't some regular pyramids that you came across. In mathematics, Pascal's pyramid is a three-dimensional arrangement of the trinomial numbers, which are the coefficients of the trinomial expansion and the trinomial distribution. Arrows show derivation of two example terms. We know it looks satisfying but we want you to cut off the apex and then, the pyramid will look something like below: Each face (orange grid) is Pascal's triangle. Imagine a pyramid, the point that makes it a perfect shape is the apex. At this point, you should know what is a pyramid, if not then we have a separate resource for the pyramid and you should first check it out. Truncated Square Pyramid (TSP) and Truncated Triangular Pyramid (TTP) are used as the foldcores to form sandwich panels.
