Question

How many bricks will be required to lay a path 120 m long and 2.4 m if a brick is 24 cm long and 15 cm wide?

Answer 1

Answer:

8000 bricks

Solution:-

Length of the path=120m

In cm

120×100=12000 cm

Breadth of the path=2.4m

In cm

2.4×100=240 cm

Now,Area of Path=length×breadth

=12000 cm ×240 cm

=28,80,000 cm^2

Length of the brick=24 cm

Breadth of the brick=15 cm

Area of brick=24 cm×15 cm

=360 cm^2

Number of brick required

$\frac{area \: of \: path}{area \: of \: brick}$

$\frac{2880000}{360}$

$8000$

Number of brick required to lay a path=8000

Answer 2

Answer:

8000 brick's

Step-by-step explanation:

path length=120m

path width=2.4m

path area=length×width =288m

brick length=24cm=.24m

brick width=15cm=.15

brick area=length ×width=.0360m

Now, Number brick's = area of path / area of brick= 8000
