The paper net of the truncated pyramid is a flat geometric figure that completely repeats the surface of the body and, when bending and gluing, allows the creation of a geometric solid.

Depending on the number of corners of the base, the truncated pyramids as well as the regular pyramids distinguish:

- triangular or trihedral pyramids;

- quadrangular or tetrahedral pyramids;

etc.

To create models of truncated pyramids of comparable sizes, you can use the property of the pyramid, when a cone can be described near the pyramid.
