The figure shown in the image provided is called a sphere. Note that a sphere can be thought of as a round ball. In geometric terms, a sphere is defined as a set of points that are a given distance from a given point. The given point is called the center of the sphere and the given distance from the center of the sphere to the set of points that form the sphere is called the radius of the sphere.

The volume of a sphere can be calculated by the formula that is shown in the second image that is provided below.

Answer:

The correct option is;

Yes, the line should be perpendicular to one of the rectangular faces

Step-by-step explanation:

The given information are;

A triangular prism lying on a rectangular base and a line drawn along the slant height

A perpendicular bisector should therefore be perpendicular with reference to the base of the triangular prism such that the cross section will be congruent to the triangular faces

Therefore Marco is correct and the correct option is yes, the line should be perpendicular to one of the rectangular faces (the face the prism is lying on).
