The pyramids are huge architectural mysteries. They were built from mastaba and limestone and several sun baked bricks. The blocks are huge.
The main material was limestone.
Engineered fill is soil or crushed stone that is compacted and used as fill. Engineered fill has much to do with the placement and compaction of the material you are using and not just the material itself.
Energy pyramids start with a producer at the bottom . Then it has the consumers at the top.
A pillow stuffing is a material used to fill out a pillow! e.g. goose feathers.
Crushed concrete or processed fill.
A square pyramid has five faces, one of which is a square and the remaining four are triangles. Conventionally such a pyramid is called a square BASED pyramid and in that context it has only one base. [That definition is used to distinguish it from a pentagonal pyramid, a hexagonal pyramid, etc.] However, any one of the five faces can be at the bottom.
One more than the number of vertices of the bottom.examples:Triangular based pyramid:4 vertices on a pyramid: three one the bottom, one on the top Square base pyramid:5 vertices on a pyramid. Four on the bottom, one on the top. Hendecagonal based pyramid12 vertices on a pyramid. Eleven on the bottom, one on the top Hope this helps!* * * * *A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n ≥ 3.
