So in this question they're asking us to say which of the following cannot be formed by an intersection of a cube and a plane.
00:12
So we have a cube and a plane.
00:15
Whenever you have an intersection of the cube and plane, the question is which of the following which is given to be a to be triangle, b to be a rectangle, c to be a point and d to be a circle.
00:42
Now what is important to realize is that a point, when it comes to a point which is the option c, it's easier to say is a zero -dimensional object.
01:05
The rest of the objects, the triangle is a two -dimensional object so you can easily draw them.
01:10
It's a triangle, this is a rectangle and you have a point and you have a circle.
01:15
So you all of the triangle, rectangle, circle has area or some sort of length but a point only has a coordinate.
01:23
Therefore it is a zero -dimensional object and which means the intersection of a cube, the cube is a three -dimensional object and a plane which is a two -dimensional object...
