If it has a square base, one. Squares don't crop up all that often.
triangular pyramid
A square based pyramid has 4 triangular faces and 1 square face.
There are many but I guess that the answer that you are looking for is a pyramid.
0, a triangular pryamid (or tetrahedron) is made up of four triangular faces.
It has 8 vertices.
6
There are many possibilities, one of which is an octagonal pyramid.
A solid figure with many sides such as a pyramid
1 squares
It is a tetrahedron which is a triangular based pyramid having 4 faces, 6 edges and 4 vertices
There are infinitely many possible answers. A square based pyramid is one.
I think 5 but if its a solid figure like pentagonal prism it got 10 and if pyramid six
A pyramid need not have any square faces. It can have at most one.
No such thing as a 'square pyramid'. A pyramid is a solid object, with one (1) square base, and four(4) triangular faces. Only one face is 'square' , the BASE. ALL pyramids have a SQUARE base, so there is no need to describe it as a 'square pyramid'. Do NOT confuse with a Tetrahedron, which is a solid object, composed of four(4) triangular faces. The base being a triangle, and three triangular faces.
At most one; it could be zero.
No, because a polyhedron is a solid with many flat faces. A heptagon is not a 3-D figure. However, a pyramid or prism would be a polyhedron.
One square and four triangles.
