# Building with Bricks Chapter Notes - Mathematics for Class 4: NCERT

Different type of bricks can be used for different purposes

1. Making houses and Buildings
2. Making floor
3. Making windows (Jharokha)
4. Making Jaali, arch etc. on main door

Some types of bricks are shown in the following picture
Step-1
Bricks are made by clay and soil dug from the earth by pouring their liquid form in Mold.
Step-2
Bricks are then arranged in long lines and kept out to dry.

Step-3
The bricks are then kept in big chimneys to make them solid and strong.

Jagriti School in Murshidabad (West Bengal) is one of the examples of making school building by bricks.
Masons got this idea after seeing old tomb of Murshid Kuli Khan.It was made three hundred years ago.

BRICK PATTERNS:
Different type of patterns can be drawn by arranging bricks on floor.

The school is proud to have such a beautiful building!
Children play and sing on it and make new patterns themselves.

MORE PATTERNS:

• Many of the above patterns are symmetrical. Lines of symmetry can be drawn across them which will divide them into mirror halves.
• Pattern E has pattern made in the form of a circle

• Many of the above patterns are also symmetrical. Lines of symmetry can be drawn across them which will divide them into mirror halves.
• Pattern J has pattern made in the form of a circle.

FACES OF A BRICK:
When you see bricks and try to draw, it looks different when viewed from different sides.
It looks like a Rectangle when you see from the front, top and the side. When viewed from the corner view you can see three sides.

ARRANGING BRICKS:

A wall can be made by arranging bricks in different patterns.
Like Munia and Zainab made two different type of walls.
A wall is stronger when bricks are put in cross pattern than a wall made by putting bricks on top of each other.

Jaali Pattern &Arch Design:
A jaali pattern can be drawn by arranging bricks like in the pictures given below.

Five types of jaali designs are shown below.

An Arch design can also made by arranging bricks in vertical layout like in a bridge and main door as shown in the pictures below.

A Special Arch:
The jaali of the window is made of thin bricks

MEASUREMENT OF BRICKS:
A brick is measured by its length,width and height.

So to get size of any brick you need its length, width and height.

• There are about One Lakh brick kilns in India.
• One lakh is 1,00,000 contain six digit 1 and five Zero (0).

PRICE CALCULATION OF BRICKS:

Example:

If 2000 rupees is the price of 1000 bricks and Bhajan required 500 bricks then how much he need to Pay.

Solution:

1000 Bricks price is = Rs 2000

1 Brick’s price is      = Rs 2000/1000

500 Bricks price is = (2000/1000) x 500

= (2) x 500 = Rs 1000

So, Bhajan needs to pay Rs 1000 for 500 bricks.

## FAQs on Building with Bricks Chapter Notes - Mathematics for Class 4: NCERT

 1. What are the advantages of using bricks for building construction?
Ans. Bricks offer several advantages for building construction. They are durable, fire-resistant, and have good thermal insulation properties. Bricks also provide excellent sound insulation, are resistant to termites, and require less maintenance compared to other building materials.
 2. Are bricks environmentally friendly?
Ans. Yes, bricks are considered environmentally friendly. They are made from natural materials such as clay and shale, which are abundant and readily available. Bricks are also recyclable and can be reused in construction or crushed and used as aggregates in other applications.
 3. How long do bricks last?
Ans. Bricks have a long lifespan and can last for several decades or even centuries with proper maintenance. The durability of bricks depends on various factors such as the quality of the bricks, the construction techniques used, and the environmental conditions they are exposed to.
 4. Can bricks be used for both exterior and interior walls?
Ans. Yes, bricks can be used for both exterior and interior walls. They provide structural stability and can withstand various weather conditions, making them suitable for external walls. Bricks also offer good thermal insulation and soundproofing properties, making them ideal for interior walls.
 5. How are bricks manufactured?
Ans. Bricks are manufactured through a process called brickmaking. It involves extracting clay or shale from the ground, shaping it into bricks using molds, and then drying and firing them in kilns to harden them. The manufacturing process may vary slightly depending on the type of bricks being produced.
