Where else have you see an arch?----------------------------------
Ans:
An arch is a typically curved structure that will function as an opening and provide structural support.
It can be seen in many places.
But I have seen the arch in the bridges, the rainbow and so on.
Which of these bricks have curved edges?
Ans:
Curved edges refer to the edges that are rounded in the edges.
So observe the rounded edge of the bricks from the diagram.
The bricks in the left corner have the curved edge and the image of that brick is given:
How many do you see of the longest brick?
Ans:
The longest brick is in the front side.
Only two of six faces are observed by me.
Thus only two faces of the longest brick are seen.
Is there any brick which has more than six faces?
Ans:
Generally bricks are of cuboid shape and consist of only six faces.
So bricks cannot have more than six faces.
Take one brick and measure it.
(a) How long is it? ---------------------------
(b) How wide is it?
(c) How high is it?
Ans:
Take a brick.
Measure the length of the brick with the ruler.
The length of the brick is about $\text{20 cm}$.
Ans:
Take a brick.
Measure the width of the brick with the ruler.
The width of the brick is about $\text{8 cm}$.
Ans:
Take a brick.
Measure the height of the brick with the ruler.
The height of the brick is about $\text{1 cm}$.
Muniya wants to make a wall $1$ meter long. How many bricks will she need to put in a line?
Ans:
Consider the length of the brick to be $\text{20 cm}$
Muniya needs to build a wall of $\text{1 m}$
We know that $\text{1 m=100 cm}$
We need $n$ number of bricks of $\text{20 cm}$ to build a $\text{100 cm}$ wall.
Thus, $20n=100$
$n=\frac{100}{20}$
$n=5$
Hence $5$ bricks are required to build a wall of $\text{1m}$in a line.
Can you guess how high the chimney is here? Is it:
(a) about 5 meters
(b) about $15$ meters
(c) about $50$ meters
Ans:
We know that the length of the brick is about $20\text{ cm}$.
From the height of the chimney, we know that the height of the chimney is very high.
So we can conclude that the chimney is about $50$ meters tall.
Here are four pictures from the brick kiln. These pictures are jumbled up. Look at them carefully. Write the correct order.
Ans:
The bricks are made from the following process,
Collecting the mud
Made mud into small parts.
Separate the mud leaving some spaces between them.
Finally arranging them one above the other.
The order given above follows.
Thus the correct sequence of the picture form brick is $\text{C, D, B, A}$
Mental Math: Bhajan buys Bricks. Bhajan went to buy bricks. The price was given for one thousand bricks. The prices were also different for different types of bricks.
Old bricks | Rs 1200 for one thousand bricks |
New bricks form Intapur | Rs 1800 for one thousand bricks |
New bricks from Brickabad | Rs 2000 for one thousand bricks |
Bhajan decided to buy the new bricks from Brickabad. He bought three thousand bricks. How much did he pay?
Ans:
Since Bhajan decided to buy bricks from Brickabad,
Cost of one thousand bricks $=Rs.2000$
Cost of $3$thousand bricks $=3\times 2000$
$=Rs.6000$
The cost of three thousand bricks from Brickabad is $Rs.6000$
Guess what he will pay if he buys $500$ bricks.
Ans:
Bhajan buys $500$ old bricks in this case.
Cost of $1000$bricks $=Rs.1200$
Cost of $500$ bricks $=\frac{1200}{2}$
$=Rs.600$
Thus the cost of $500$ old bricks is $Rs.600$.
