Question

What is the name of the object given?
 

A). Triangular prism
B). Square prism
C). Octagonal prism
D). None of these

Answer 1

Hint: Here we need to determine the shape of a given figure. We will analyze the shape of the figure and count its sides. We will use the fact that each of the corresponding edges of 2 bases joined by 4 sides of a polygon normally rectangle and in this figure triangle has 3 sides. And in square prism three dimensional cuboid bases and top are equal squares.

Complete step-by-step solution:
Here, we need to determine the shape of the given figure.
A prism consists of two n-sides polygonal bases placed exactly in front of each other at some distance and corresponding edges of 2 bases are joined by 4 sided polygon, normally rectangular.
So, the prism is known by its n-sides polygonal bases
But in the given figure base is 3 sided triangle
In general the base of a prism can be anything like triangle, square, hexagonal, pentagonal, octagonal etc.
As you can see in this figure there is an triangular base and we know that a triangles is defined as triangles of 3 sides,
We can see in the given figure on each side of this triangle the corresponding edges of 2 bases are joined by 4 sided polygons, normally rectangles.
So, we can say that this is a triangular prism.
Hence the correct option is “option A”.

Note: Most students mistakenly believe that a prism and a pyramid are the same thing, although the two are actually quite distinct. A pyramid is a polyhedron made up of a polygon base and an apex point. A pyramid is known by its n-sides polygonal base. In pyramids joining faces is a triangle not a parallelogram.
