A hexagonal pyramid has 6 triangular faces that meet at a point. It has 6 triangles and 1 hexagonal base.
A square pyramid is a polyhedron with a square base and triangular sides that meet at a point at the top. This gives this pyramid five faces.
pyramid
The object you are describing is a square pyramid. A square pyramid has a square base and four triangular faces that meet at a single point called the apex. Each triangular face is formed by connecting a vertex of the base square to the apex. The total number of faces in a square pyramid is 5 - 1 square base and 4 triangular faces.
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.
A pyramid would fit the given description
A pyramid with a square base is called a square pyramid. It is a three-dimensional shape that has a square as its base and four triangular faces that meet at a point called the apex.
The flat surfaces on a pyramid are called faces. A pyramid has one base and triangular faces that meet at a single point called the apex. On a cube or rectangular prism, the flat surfaces are called faces as well. But unlike a pyramid, a cube has six square faces, while a rectangular prism has two rectangular bases and four rectangular faces.
a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point
A hexagonal pyramid has 6 triangular faces that meet at a point. It has 6 triangles and 1 hexagonal base.
A square pyramid is a polyhedron with a square base and triangular sides that meet at a point at the top. This gives this pyramid five faces.
A rectangular pyramid has a rectangular base and four triangular faces that meet at a single point called the apex. A square pyramid, on the other hand, has a square base and four triangular faces that meet at a single point. The key difference is in the shape of the base - rectangular pyramid has a rectangular base, while a square pyramid has a square base.
The shape you are describing is a triangular pyramid. A triangular pyramid has a base that is a triangle and three triangular faces that meet at a single point called the apex. The base of the pyramid is a rectangle, which is a quadrilateral with four right angles. The triangular faces of the pyramid connect the vertices of the base to the apex.
A solid figure with a polygonal base and triangular faces that meet at a common point.
The description given fits that of a pyramid
That sounds like a square-based pyramid.
A pentagonal pyramid.
