Question

a solid is cut by a plane that is parallel to its base, forming a two-dimensional cross section in the shape of a rectangle. which of the following solids could have resulted in that cross section?

answer

○ triangular pyramid

○ rectangular prism

○ right cone

○ right hexagonal prism

Explanation:

1. A triangular pyramid's parallel cross-section to its base is a triangle, not a rectangle.
2. A rectangular prism has rectangular bases; a plane parallel to its base will cut a rectangular cross-section that matches the base shape.
3. A right cone's parallel cross-section to its base is a circle, not a rectangle.
4. A right hexagonal prism's parallel cross-section to its base is a hexagon, not a rectangle.

Answer:

rectangular prism
