Question

How many bricks are required to build a wall of height
2.88 m and width 50 cm, if the length of each brick is
9.
12 cm and breadth is 10 cm?​

Answer 1

Answer:

120 bricks are required

Step-by-step explanation:

GIVEN:

Height of the wall = 2.88 m

Width of the wall = 50 cm

The length of each brick = 12 cm

The breadth of each brick = 10 cm.

TO FIND:

How many bricks are required to build a wall

SOLUTION:

H = 2.88 M = 280 cm

W = 50 cm

The area of the wall =

$A_{w}$ = H * W

$A_{w}$ = 280 * 50

$A_{w}$ = 14400 $cm^{2}$

Dimension of the brick =

L = 12 cm

B = 10 cm

The area of the brick =

$A_{b}$ = L * B

$A_{b}$ = 12 * 10

$A_{b}$ = 120 $cm^{2}$

Now, to find the number of bricks =

$x =$ $\frac{A_{w} }{A_{b} }$

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

$x = 120 bricks$

THEREFORE, NUMBER OF BRICKS WHICH ARE REQUIRED = 120 bricks
