Answer 1

1200 bricks.............

Answer 2

Answer:

Number of bricks are 120.

Step-by-step explanation:

Given : Wall of height 2.88 M and width 50 cm. if the length of each brick is 12 cm and breadth is 10 cm.

To find : How many bricks are required to build a Wall ?

Solution :

Dimension of the wall,

H=2.88m=288 cm

W=50 cm

The area of the wall is

$A_w=W\times H$

$A_w=50\times 288$

$A_w= 14400 cm^2$

Dimension of the brick,

L=12 cm

B=10 cm

The area of the brick is

$A_b=L\times B$

$A_b=12\times 10$

$A_b= 120 cm^2$

Number of bricks required is

$n=\frac{A_w}{A_b}$

$n=\frac{14400}{120}$

$n=120$

Therefore, Number of bricks are 120.
