Question

What shape best describes the cross section cut parallel to the base of a right rectangular prism?

Rectangle

Parallelogram

Square

Trapezoid

Answer 1

The cross section of a rectangular prism is a rectangle. The cross section is the shape that results from cutting straight through a prism.

Answer 2

To answer this question, it is enough to find the volume of a rectangular prism.
The volume of a rectangular prism is:

`V = Ab * h`
Where,
Ab: base area
h: height
The area of the base is:

`Ab = w * l`
Where,
w: width
l: long
We observe that the area of the base is a rectangle, therefore, the section parallel to the base is also a rectangle.
Answer:
The cross section cut parallel to the base of a right rectangular prism is:
Rectangle
