Chapter 1: Building with Bricks

Ans:

By observing the above given patterns, I observe that pattern J is made in a circle.

In which pattern can you show mirror halves?

Ans:

Mirror halves objects are those in which the objects are the same in both sides of the symmetry line. 

Hence draw the symmetry line through the center of the object and see if we obtain mirror halves.

Hence the mirror halves can be shown in $5$patterns. They are $\text{A, B, H, I, J}$.

The line can be drawn to show the mirror halves as shown below:

Ans:

Generally the brick will be in the shape of a cuboid. So every brick has $6$ faces.

Is any face a square?

Ans:

We know that the brick is of cuboid shape.

The cuboid is formed of six rectangular faces.

So there is no square face in cuboid.

Draw the smallest face of the brick.

Ans:

The smallest side of the brick is the side with a breadth and height and it can be drawn as follows:

Ans:

A brick is of the shape of a cuboid of cube. 

Thus the shape of the brick consists of a rectangle and square. 

So insert the $\left(  \right)$ symbol in the shape of rectangle and square.

These are the shapes of squares and rectangles which can make the faces of bricks.

Ans:

The brick is in the shape of a cuboid. 

So from the diagram, the shape of the cuboid is found.

Hence the shape of the cuboid has been ticked.

Ans:

To draw the box with three faces, just flip the box and we obtain the box with three faces.

Hence this box diagram with three faces has been drawn.

Ans:

The brick is a 3D shape of cuboid.

And so it is impossible to show the $4$ faces of the brick in a sheet of paper.

Missing Question 3:

What do you think? Which wall will be stronger?

Ans:

Zainab did not interlock the brick pattern. 

But Muniya places her bricks in an interlocking pattern. 

So the walls of Muniya will be stronger since her bricks are tightly packed with each other.

Ans:

Observe the patterns.

The brick in the first picture has one brick horizontally placed between the two vertical placed bricks.

The bricks in the third picture are more tightly packed than that of bricks in the second picture.

Now match the photo of each wall with the correct drawing below:

Ans:

As described in the above question, match the bricks with the interlocking patterns in the patterns given in this question.

Hence the bricks have been matched with its pattern.

Ans:

The above building seems to have five different ‘Jaali’ patterns.

The pillar is made of one pattern. 

The walls of building made of one pattern, 

The upper layer of the balcony is made of one pattern.

The balcony layer with designs made of one pattern.

And the above floor with design on both sides made of one pattern.

So five patterns of “Jaali” are there in the above building.

Ans:

To make our own ‘jaali’ pattern, we can choose any side of the above given ‘jaali’ pattern.

Our ‘jaali’ pattern is made in the center with some designs on the wall.

Ans:

The Jharoka is a stone window that is projecting from the wall of the building.

To draw the jharokha pattern and shade them in black:

Hence the wall with jharokha pattern has been drawn.
