- Variables:
<blockquote>l ⇒ length of edges of the cubic pyramid</blockquote>
- The hypervolumes of a cubic pyramid are given by:
<blockquote>total edge length = 20l<br> total surface area = Unknown<br> surcell volume = Unknown<br> bulk = l<sup>4</sup>4<sup>-1</sup></blockquote>
- The realmic cross-sections (n) of a cubic pyramid are:
<blockquote>[!x,!y,!z] ⇒ triangle<br> [!w] ⇒ square</blockquote>
Net
The net of a cubic pyramid is a cube surrounded by six square pyramids.
