22.	How many bricks of dimensions 24 cm × 12 cm × 8 cm are required to make a wall 10 m long, 4 m high and 36 cm thick?
Answer» Question :- How MANY bricks of DIMENSIONS 24cm x 12cm x 8cm are required to make a wall of 10m long , 4M high, 36 cm thick ? Answer :- Given :- Dimensions of the brick is 24cm x 12cm x 8cm Dimensions of the wall is 10m x 4m x 36cm Required to find :- Number of bricks required ? Units Conversion :- Before solving this question we need to convert some units from one unit to another . Here, we have to change the dimensions of the brick from cm to meters similarly the thickness of the wall should also be converted . So, Dimensions of the brick = 24cm x 12cm x 8cm we know that $\tt{ 1 \; centimetre = \dfrac{1}{100} meters }$ So, 24cm = 24/100 = 0.24 m 12cm = 12/100 = 0.12 m 8cm = 8/100 = 0.08 m Similarly, Thickness of the wall = 36cm => 36cm = 36/100 = 0.36 m Formula used :- $\leadsto{\boxed{\textsf{Volume of a cuboid }{\mathsf{\;= length \times Breadth \times Height }}}}$ Solution :- Given :- Dimensions of the brick = 0.24m x 0.12m x 0.08m So, Length of the brick = 0.24 m Breadth of the brick = 0.12 m Height of the brick = 0.08 m By using the formula , $\leadsto{\boxed{\textsf{Volume of a cuboid }{\mathsf{\;= length \times Breadth \times Height }}}}$ ➜ volume of the brick = 0.24 m x 0.12 m x 0.08 m ➜ Volume of the brick = 0.002304 m³ Similarly, We are also given with, Dimensions of the wall = 10 m x 4 m x 0.36 m So, Length of the wall = 10 m Breadth of the wall = 4 m Height of the wall = 0.36 m ➜ Volume of the wall = 10 m x 4 m x 0.36 m ➜ Volume of the wall = 14.4 m³ Now we have to find the number of bricks required . So, No. of bricks required is equal to Volume of the wall by Volume of the brick . $\tt{No. \; of \; bricks \; required = \dfrac{Volume \; of \; the Wall}{Volume\; of \; the \: brick }}$ So, $\longrightarrow{\tt{ No. \; of \; bricks \; required = \dfrac{14.4 \; m^3 }{0.002304 \;m^3 }}}$ ➜ m³ get cancelled in both numerator and denominator $\longrightarrow{\tt{No. \; of \; bricks \; required = \dfrac{14.4 }{0.002304 }}}$ ➜ Multiply numerator and denominator with 10,00,000 $\leadsto{\tt{No.\; of \;bricks \; required = \dfrac{1,44,00,000}{2304}}}$ $\implies{\red{\tt{ No. \; of \; bricks \; required = 6,250\; bricks }}}$ $\large{\leadsto{\tt{\therefore{No. \; of \; bricks \; required = 6,250 \; bricks }}}}$

How many bricks of dimensions 24 cm × 12 cm × 8 cm are required to make a wall 10 m long, 4 m high and 36 cm thick?

Answer»

Question :-

How MANY bricks of DIMENSIONS 24cm x 12cm x 8cm are required to make a wall of 10m long , 4M high, 36 cm thick ?

Answer :-

Given :-

Dimensions of the brick is 24cm x 12cm x 8cm

Dimensions of the wall is 10m x 4m x 36cm

Required to find :-

Number of bricks required ?

Units Conversion :-

Before solving this question we need to convert some units from one unit to another .

Here, we have to change the dimensions of the brick from cm to meters similarly the thickness of the wall should also be converted .

So,

Dimensions of the brick = 24cm x 12cm x 8cm

we know that

$\tt{ 1 \; centimetre = \dfrac{1}{100} meters }$

So,

24cm = 24/100 = 0.24 m

12cm = 12/100 = 0.12 m

8cm = 8/100 = 0.08 m

Similarly,

Thickness of the wall = 36cm

=> 36cm = 36/100 = 0.36 m

Formula used :-

$\leadsto{\boxed{\textsf{Volume of a cuboid }{\mathsf{\;= length \times Breadth \times Height }}}}$

Solution :-

Given :-

Dimensions of the brick = 0.24m x 0.12m x 0.08m

So,

Length of the brick = 0.24 m

Breadth of the brick = 0.12 m

Height of the brick = 0.08 m

By using the formula ,

$\leadsto{\boxed{\textsf{Volume of a cuboid }{\mathsf{\;= length \times Breadth \times Height }}}}$

➜ volume of the brick = 0.24 m x 0.12 m x 0.08 m

➜ Volume of the brick = 0.002304 m³

Similarly,

We are also given with,

Dimensions of the wall = 10 m x 4 m x 0.36 m

So,

Length of the wall = 10 m

Breadth of the wall = 4 m

Height of the wall = 0.36 m

➜ Volume of the wall = 10 m x 4 m x 0.36 m

➜ Volume of the wall = 14.4 m³

Now we have to find the number of bricks required .

So,

No. of bricks required is equal to Volume of the wall by Volume of the brick .

$\tt{No. \; of \; bricks \; required = \dfrac{Volume \; of \; the Wall}{Volume\; of \; the \: brick }}$

So,

$\longrightarrow{\tt{ No. \; of \; bricks \; required = \dfrac{14.4 \; m^3 }{0.002304 \;m^3 }}}$

➜ m³ get cancelled in both numerator and denominator

$\longrightarrow{\tt{No. \; of \; bricks \; required = \dfrac{14.4 }{0.002304 }}}$

➜ Multiply numerator and denominator with 10,00,000

$\leadsto{\tt{No.\; of \;bricks \; required = \dfrac{1,44,00,000}{2304}}}$

$\implies{\red{\tt{ No. \; of \; bricks \; required = 6,250\; bricks }}}$

$\large{\leadsto{\tt{\therefore{No. \; of \; bricks \; required = 6,250 \; bricks }}}}$

Please solve this please if you do I will mark your answer as brainliest and also follow upls solve these 2 questions

Answer»

Answer:

* 12 Sides of polygon total interior Angle = (12-2) × 180

= 10 ×180

= 1800 degree

Each angle = 1800 / 12

Each angle = 150 degree

THEREFORE each Exterior Angle = (360 - 150) degree

Each Exterior Angle = 210 degree

Then

* 18 sides of polygon total interior angle = (18 -2) × 180

= 2880 degree

Each Angle = 2880 / 18

Each Angle = 160 degree

Therefore each exterior angle = (360 - 160) degree

Each exterior Angle = 200 degree

* QUADRILATERAL POLYGON IS A CONCAVE BECAUSE TOTAL INTERIOR ANGLES ARE GREATER

THAN 180 DEGREE...

47.	1. Four bells toll at intervals of 8,9,12 and 15 minutes respectively. If they toll together at 3 p.m.,when will they toll together next ? Explain by using LCM Common Division Method and explain how 8,9,12 and 15 is change into 9.p.m?If you give correct answer I will make you brainlist.
Answer» Answer: 9 PM Step-by-step explanation: Given that, FOUR bells toll after an interval of 8,9,12,15 minutes ,respectively. These bells begin to toll together at 3.p.m. We have to find the time at which they toll again. For this, first we have to calculate the L.C.M of given numbers. FACTORS of 8 are 2 x 2 x 2 Factors of 9 are 3 x 3 Factors of 12 are 2 x 2 x 3 Factors of 15 are 3 x 5 Common factors are 2 x 2 x 3 x 2 x 3 x 5 Hence, L.C.M = 360 Which shows that the four balls toll together after 360 minutes. Now we convert these minutes into hours. We know that, 60 minutes = 1 hour 360 minutes = (1 / 60 ) . 360 = 6 hours As it is given that the bells begin to toll together at 3 p.m So next toll will be after 6 hours. Thus 3 p.m + 6 hours which clearly shows that the bells toll together again at 9 p.m

Answer»

Answer:

9 PM

Step-by-step explanation:

Given that, FOUR bells toll after an interval of 8,9,12,15 minutes ,respectively.

These bells begin to toll together at 3.p.m. We have to find the time at which they toll again.

For this, first we have to calculate the L.C.M of given numbers.

FACTORS of 8 are 2 x 2 x 2

Factors of 9 are 3 x 3

Factors of 12 are 2 x 2 x 3

Factors of 15 are 3 x 5

Common factors are 2 x 2 x 3 x 2 x 3 x 5

Hence, L.C.M = 360

Which shows that the four balls toll together after 360 minutes.

Now we convert these minutes into hours.

We know that,

60 minutes = 1 hour

360 minutes = (1 / 60 ) . 360

= 6 hours

As it is given that the bells begin to toll together at 3 p.m

So next toll will be after 6 hours.

Thus 3 p.m + 6 hours

which clearly shows that the bells toll together again at 9 p.m
