the typical 4 sided pyramid with a square base has 8 edges.
A cube has 12 edges. A 4-sided pyramid has 8 edges. A 3-sided pyramid has 6 edges. There are also other pyramids with more sides.
if its a four sided pyramid then four. if its a three sided pyramid then four.
If by "side" you mean face, you might be referring to a heptagonal pyramid (a pyramid with eight faces).If by "side" you mean edge, you might be referring to a tetragonal pyramid (a pyramid with eight edges).Or, if you mean it has an eight-sided base, your answer would be an octagonal pyramid (a pyramid with an eight-sides base).
If side refers to 'face', then the pyramid would be a quadrilateral pyramid with 8 edges. If side refers to the base of the pyramid, it would be a pentagonal pyramid with 10 edges.
A 7 sided pyramid would be called a heptahedral or heptahedron.
Octagonal pyramid
the typical 4 sided pyramid with a square base has 8 edges.
A cube has 12 edges. A 4-sided pyramid has 8 edges. A 3-sided pyramid has 6 edges. There are also other pyramids with more sides.
An octagonal pyramid would have 9 sides: an octagon as the base and 8 triangles from that base to the apex of the pyramid.
a 6 or 8 sided figure
if its a four sided pyramid then four. if its a three sided pyramid then four.
If by "side" you mean face, you might be referring to a heptagonal pyramid (a pyramid with eight faces).If by "side" you mean edge, you might be referring to a tetragonal pyramid (a pyramid with eight edges).Or, if you mean it has an eight-sided base, your answer would be an octagonal pyramid (a pyramid with an eight-sides base).

If side refers to 'face', then the pyramid would be a quadrilateral pyramid with 8 edges. If side refers to the base of the pyramid, it would be a pentagonal pyramid with 10 edges.
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.
I would guess it is a pyramid that has a seven-sided polygon as its base.
