Question

The net of a triangular prism has ____ triangles.

A. 1
B. 2
C. 3
D. 4

Answer 1

Hint:To solve this question, we should know that a prism is a solid body which has two opposite ends of the same shape and all the rest faces as parallelograms. And the name of the prism is given on the basis of the shape of the ends of the prism.

Complete step-by-step answer:
In this question, we have been asked to find the number of triangular faces of a triangular prism. To name it we should know that a prism is nothing but a solid body which has its 2 opposite faces of the same shape and the rest faces as parallelograms. And that the name of the prism is given based on the shape of the ends of the prism other than the parallelogram. Like, if two opposite faces of the prism are pentagonal in shape, then the name of the prism will be pentagonal prism. So, the triangular prism will be something which has two opposite faces of triangle shape and all the rest faces of parallelogram shape.
Therefore, we can say that the triangular prism will have 2 net triangular faces. Hence, option B is the correct answer.

Note: We can also solve this question by directly looking at the figure of the given triangular prism. If we name them, then it will be something like the figure below,

So, from the above figure, we can say that faces AED, BFC are the only triangles, whereas faces ABCD, CDEF and ABFE are parallelograms, which means that there are 2 triangles in a triangular prism.
