Question

Which three-dimensional figure does not have a possible rectangular cross-section?

A: square pyramid
B: Cone
C: triangular prism
D: cylinder

Answer 1

B. Cone

Explanation:

Step 1: Define.

• A cone only has cross-sections of a triangle, hyperbola, ellipse, circle, and parabola.
• A cylinder has cross-sections of a rectangle and circle.
• A square pyramid is a triangle, square, trapezoid, and rectangle.
• A triangular prism has cross-sections of a rectangle and a triangle.

Step 2: Conclude.

I, therefore, believe that a cone does not have a possible rectangular cross-section.

Answer 2

Come because it’s circular on the bottom and has intersecting slants on every side
