Question

A right rectangular prism is sliced perpendicular to its base as shown in the figure.

Answer 1

The shape of the resulting two-dimensional cross section is a rectangle. :) 

Answer 2

Answer:

The shape of the resulting two dimensional cross section will be rectangle

Step-by-step explanation:

The shape of the resulting two dimensional cross section will be rectangle.

Reasoning:

Let's suppose, you have a rectangular cake in front of you and you are given a knife to cut it in half. When you slice the cake from the half and when you analyze the side view of that half cake you will find a two dimensional rectangle shape.

For example, if you have 52 two dimensional rectangular cards in your hand and if you asked to join all these cards together then as a result, you will get a 3 dimensional deck of cards consisting of 52 rectangle cards joined together. And if you slice out one card from that deck you see it as 2 dimensional rectangular card because it was the building block of that 3D deck.

Hope, it may help!
