Detailed Solution

Concept- Assume that the cube's edge length is a unit. Each face of a cube has four edges, each of which is perpendicular to the others and has a length of one unit. Therefore, we can conclude that the cube's faces are all square in shape. Utilise the fact that a cube has six faces now. Get the number of squares the cube contains by solving the problem further.
According to the question, we are given a cube and we have to figure out the number of squares that the cube contains.
First of all, let us assume that the edge length of the cube is a units ……………(1)
We know the property that edges of a cube are equal to each other …………..(2)
Now, from equation (1) and equation (2), we can say that the length of each edge of the cube is a unit.

A Cube is three-dimensional whereas a square is a two-dimensional figure. Every face of a cube has four edges and the length of each edge is equal to a
units and each edge is perpendicular to each other. So, we can say that every face of the cube is of square shape.
Here, we are asked the number of squares. In other words, we can say that the number of faces of a cube is equal to the number of squares…………..(3)
We also know the property that a cube has six faces ……………(4)
Now, from equation (3) and equation (4), we get
The number of squares that a cube contains is 6.
Hece, option 2 is correct.
