Hint: In this question, we need to find the number of faces a cuboid has. For this, we will first draw a cuboid and then count all the faces it can have. For better understanding, we can also use a physical object which is in the shape of cuboid to find out answer.
Complete step-by-step answer:
Here we need to find the number of faces of cuboid. So let us first draw a cuboid. A cuboid has faces in the shape of rectangle. The diagram for a cuboid looks like this:
We have marked all the corners or the vertices of the cuboid. Faces are the rectangles that cuboid has. So let us start counting them.
First rectangle that we can see is ABCD which is one of our face.
Similarly, we have a rectangle at back EFGH which is our second face.
Now let us rotate our cube so that we can see our face in the shape of rectangle only.
Now we have rectangle ADEH and DCFG which are our third and fourth faces of the cuboid.
Again rotating the cuboid we can see,
Now we have two more rectangles DCFE and ABGH which are our fifth and sixth faces of the cuboid.
Hence all faces have been counted, so we can see that we have six faces of a cube:
So, the correct answer is “Option B”.
Note: Students often get confused between faces and edges of the cuboid. Faces are the rectangle and edges are the lines of the cuboid. Students should check the answer by taking any cuboidal shape in their surroundings such as a book or a match box and then count the faces it has.
