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.
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.
The answer depends upon what is meant by "have 3 triangles?" The definition of a pyramid is "a solid having a polygonal base, and triangular sides that meet in a point." (Random House Webster's Unabridged Dictionary) Typical pyramids have a 4-sided quadrilateral base and 4 triangular sides, which means that it can be loosely said to also "have" 3 triangles as well as "have" 4 triangles. A pyramid with a triangular base would also have 3 triangular sides. If we include the shape of the base as a side of the pyramid, then no pyramid would have exactly 3 "sides."
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.
No because a quadrilateral is a 4 sided 2 dimensional polygon whereas a pyramid is a 3 dimensional polyhedron
A 3-sided pyramid.
A tetrahedron (a triangulat 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.

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.

i am not sure, but i think it is 4 sided.
4 sided (or perhaps 5 if you count the base). The base is a square and the four triangular faces rise off each of the 4 edges and meet in a point at the top.
