How many edges does a cylinder has?
  • a)
    0
  • b)
    3
  • c)
    2
  • d)
    4
Correct answer is option 'C'. Can you explain this answer?

Glitz Classes answered
Two edges. A cylinder is a three-dimensional shape. Therefore, a cylinder has two linear faces and one curved face. It has two edges, each corresponding to the bottom and the upper face.

Choose the odd one out.
  • a)
    Cone
  • b)
    Cube
  • c)
    Cylinder
  • d)
    Circle
Correct answer is option 'D'. Can you explain this answer?

Glitz Classes answered
4. Circle
Explanation:
  • Cone, Cube, and Cylinder are all 3-dimensional shapes.
  • Circle is a 2-dimensional shape.
Thus, Circle is the odd one out.

It has six flat faces and twelve straight edges
  • a)
    Square
  • b)
    Cube
  • c)
    Cylinder
  • d)
    Cone
Correct answer is option 'B'. Can you explain this answer?

A Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges. It is also said to be a regular hexahedron. 

Match the shape of following objects:
  • a)
    A-1
    B-2
    C-3
    D-4
    E-5
  • b)
    A-5
    B-2
    C-1
    D-3
    E-4
  • c)
    A-2
    B-3
    C-4
    D-5
    E-1
  • d)
    A-3
    B-1
    C-5
    D-2
    E-4
Correct answer is option 'B'. Can you explain this answer?

A. A diceCube
  • A dice is a classic example of a cube because it has six equal square faces. Each face of the dice is a square, and all the edges are of equal length.
B. A pencil boxCuboid
  • A pencil box usually has a cuboid shape, which means it has rectangular faces. Unlike a cube, the length, width, and height of a cuboid are generally different.
C. A Black-boardRectangle
  • A blackboard has a flat surface, and it is generally rectangular in shape, with two opposite sides longer than the other two. This makes it a perfect example of a rectangle.
D. A Birthday capCone
  • A birthday cap has a conical shape. It has a circular base and a pointed top, which are the main features of a cone.
E. A Bottle capCircle
  • A bottle cap is typically circular when viewed from above. It has a round shape, making it an example of a circle.

In this tan gram figure how many triangles do you observed?
  • a)
    6
  • b)
    5
  • c)
    7
  • d)
    1
Correct answer is option 'A'. Can you explain this answer?

In this  figure, there are a total of six triangles. I can see two small ones. Next,
 I can see one large triangle. Also, there are three triangles that are medium-sized.
 Thus, there are six triangles in total.

Identify who am I? I have one plane face which is my base. I have one curved face and one vertex.
  • a)
    Square
  • b)
    Rectangle
  • c)
    Cone
  • d)
    Cuboids
Correct answer is option 'C'. Can you explain this answer?

Identifying the Cone
To understand why the correct answer is option 'C' (Cone), let's break down the characteristics of the shapes mentioned.
Understanding the Shapes
- Square:
- Has four equal straight sides.
- No curved faces or vertices.
- Rectangle:
- Has four sides, opposite sides being equal.
- Also lacks a curved face and vertices.
- Cuboid:
- A three-dimensional shape with six rectangular faces.
- Composed entirely of flat surfaces, no curved face or vertex.
- Cone:
- Has one flat circular base (the plane face).
- Features a single curved surface that wraps around to the apex.
- Contains one vertex at the top where the curved surface meets.
Key Characteristics of a Cone
- Plane Face:
- The circular base serves as the single flat face of the cone.
- Curved Face:
- The surface that extends from the base to the vertex is curved.
- Vertex:
- The point at the top of the cone, where the curved surface converges.
Conclusion
These unique characteristics confirm that the cone is the only shape among the options that has one flat base, one curved face, and one vertex. This makes option 'C' the correct choice. Understanding these geometric properties helps in identifying various shapes effectively.
