What is the name of the object given .

A.Pentagonal pyramid
B.Hexagonal pyramid
C.Triangular pyramid
D.None of these

Hint: Here we need to determine the shape of the given figure. We will analyze the shape of the figure and count its sides. We will use the fact that a pentagon has 5 sides, a hexagon has 6 sides and a triangle has 3 sides.

Complete step-by-step answer:
Here we need to determine the shape of the given figure.
A pyramid is a three dimensional, geometric figure that has a triangular outer surface and the base can be triangular, hexagonal, pentagonal etc.
We know that the pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apex. A pyramid is known by its \[n\]−sides polygonal base.
In the given figure, there is a colored pentagonal base and we know that a pentagon is defined as the polygon of 5 sides.
We can see that on each side of this pentagon there lies a triangle and all these triangles meet at the vertex i.e. the apex.
So, we can say that this is a pentagonal pyramid.
Hence, the correct option is option A.

Note: Most of the students have a misconception that a pyramid is the same as a prism. But it is worth knowing that these two are actually different. A prism is also a polyhedron that is made up of a polygonal base but the joining faces form a parallelogram but not a triangle.
