Question

A plane intersects a rectangular pyramid horizontally as shown. Describe the cross-section. A) circle B) rectangle C) trapezoid D) triangle

Answer 1

A plane cuts horizontally across a rectangular pyramid will always be a rectangle. (Answer B)

Answer 2

B. Rectangle

Explanation:

We are given that,

'The plane intersects the rectangular pyramid'.

'A rectangular pyramid is a three-dimensional object with rectangular as the base and triangles as the sides'.

So, a plane intersecting a rectangular pyramid horizontally will be parallel to the rectangular base.

Thus, the cross-sectional plane will be a rectangle.

Hence, option B is correct.
