We are going to talk about about fundamental strong shapes. We see quite a lot of strong objects in our environment. 

We all know these objects. If we transfer them, elevate them and contact them, they continue to be the identical.

Objects round us, which don’t change their form simply, are referred to as SOLIDS.

All these objects want house for storing them. We additionally name them Three-Dimensional (3-D) Shapes.

Stable objects have a number of shapes like the next.

Go searching and title the solids you see close to you.

1. Match the objects with related form.

We, now examine some vital strong shapes.

Stable Shapes:

It is a dice. A dice has 6 sq. faces. It has 12 edges. It has 8 corners.

It is a cuboid. A cuboid has 6 rectangular faces. It has 12 edges. It has 8 corners.

It is a cone. A cone has 1 flat face and a curved face. Cone has 1 nook.

It is a cylinder. A cylinder has 2 flat faces. It has 1 curved face. It has no corners.

It is a sphere. Sphere has no flat faces. Sphere has solely a curved face. Sphere has no corners.

Stable shapes are fats however not flat like a sheet of paper.

This soccer is fats however not flat. So, it’s a strong form or a 3-D form. This circle is flat. So, this isn’t a strong form.

This circle is flat. So, this isn’t a strong form.

Allow us to be taught

All shapes like a cuboid are referred to as cuboidal shapes.

All shapes like a cylinder are referred to as cylindrical shapes.

All shapes like a cone are referred to as conical shapes.

All shapes like a sphere are referred to as spherical shapes.

All shapes like a dice are referred to as cubical shapes.

2. Match the shapes with their properties.

(i)

I’m a strong form. I’ve two flat faces.   I’ve one curved face.

(a)

(ii)

I’m a aircraft form. I’ve one curved aspect. I’ve no corners.

(b)

(iii)

I’m a strong form. I’ve six sides. All my sides are equal in size.

(c)

(iv)

I’m a aircraft form. I’ve 4 sides and 4 corners. My two reverse sides are equal.

(d)

(v)

I’m a strong form. I’ve one flat face and a curved face. I’ve one nook.

(e)

Primary Distinction Between Dice and Cuboid:

Entrance, Again, High and Backside – 4 faces are identical of 1 sort. Left Finish, Proper Finish – 2 identical faces however totally different from different 4 faces.	It has 6 faces.               All six are of identical sort.

3. Write T for true and F for false statements.

(i) A cuboid has six faces.

(ii) A sphere has one face and one nook.

(iii) A carrot is cylindrical in form.

(iv) A cylinder has three faces.

(v) A shuttlecock seems to be like a cone.

(vi) Each strong has at the least one face.

(vii) Each a cylinder and a cone have three faces.

Reply:

3. (i) T

(ii) F

(iii) F

(iv) F

(v) T

(vi) T

(vii) F
