A 7 sided pyramid would be called a heptahedral or heptahedron.

Pyramid
the real name of the great pyramid is the pyramid of KHUFU. It is also the biggest pyramid in all of Egypt with a height of 441 feet!
The first classic "smooth sided" pyramid shape was attempted by the Pharaoh Sneferu, who founded the 4th Dynasty of the Old Kingdom. Sneferu reigned from either 24-48 years, around 2600BCE, and during this time he was responsible for three separate pyramids. His first pyramid, the Medium Pyramid seems to be the first attempt at the classic pyramid. The Medium Pyramid is famous because it appears to have collapsed and was never finished. Sneferu's second attempt was the Bent Pyramid, which gets it name from the sharp angle its sides take about halfway up the sides. The third pyramid that Sneferu attempted is the Red Pyramid and is the first classical pyramid and was the tallest manmade structure in the world until Khufu's Great Pyramid at Giza was constructed.
Triangular Pyramid.
A rectangle pyramid is a 4 sided pyramid (4 sided in the triangles) with a base of a rectangle. An Egyptian pyramid is a great example of a rectangular pyramid.
pentagonal pyramid
I suppose it would be a 4 sided pyramid. * * * * * No. A quadrangle is a quadrilateral.
If you mean a pyramid with a four sided base, it is a square pyramid. If you mean one with four faces, it is a tetrahedron.
i am not sure, but i think it is 4 sided.
a four sided pyramid distributes the weight more, so that would be it
A pyramid is usually a 4 sided figure but a cuboid is not. Also, the 4 sided pyramid all the faces are triangle but the cuboid has 2 square faces and 4 rectangle faces
4-sided pyramid.

Octagonal pyramid
A six sided cone is a pyramid technically, and it would be a hexagonal pyramid (if six sides does not include base) or a pentagonal pyramid (if including base.)
