Answer:
Triangular prism
Step-by-step explanation:
A 3D prism is a solid shape with two congruent parallel polygonal bases connected by a series of rectangular or parallelogram-shaped faces known as lateral faces.
Cross sections of a 3D prism are typically parallel to its base.
Therefore, as the given cross section is a triangle, the bases of the prism are triangles, and so the prism is a triangular prism.
A triangular prism is a three-dimensional geometric solid that consists of two congruent triangular bases and three rectangular (or parallelogram-shaped) lateral faces connecting the corresponding vertices of the bases. It has a total of 5 faces, 9 edges, and 6 vertices.
