What cross-section do you get when you cut a brick vertically?
A) Circle
B) Triangle
C) Cube
D) None of these

Hint: We will solve this question with the help of figures. At first, we will consider a figure of a brick. Then we will consider figure in which it is cut into two pieces, then we will check out of four options, that when the brick is cut we get circle, triangle or cube, cross- section, if not any of these, then we will choose the last option i.e., none of these, hence we will get our required answer.

Complete step-by-step answer:
We need to find that if a brick is cut vertically, then what cross-section will we get.
Now, let us consider a figure of brick, to understand better.


Here, we can see that the brick is in the form of a cuboid. Now let us consider a figure of brick that is cut vertically.

In the above figure, we can see that the brick is cut vertically.
Now let us consider the figure of a brick which has already been cut into two pieces vertically.

Here, we can see that the cross-section of brick is rectangle. So, when we cut a brick vertically, we get a rectangular cross-section.

Hence, option (D) None of these, is correct.

So, the correct answer is “Option D”.

Note: Students can solve this question, by taking a full brick, and then cut into two pieces with the help of an adult. Then check the cross-section of either one of the pieces, whether it is circle, square, cube, rectangle, etc. But remember one thing that brick is a three - dimensional shape but when we cut it into pieces, the cross- section will always be a two – dimensional shape.
