Answers
Step-by-step explanation:
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 HA
w
=W×H
A_w=50\times 288A
w
=50×288
A_w= 14400 cm^2A
w
=14400cm
2
Dimension of the brick,
L=12 cm
B=10 cm
The area of the brick is
A_b=L\times BA
b
=L×B
A_b=12\times 10A
b
=12×10
A_b= 120 cm^2A
b
=120cm
2
Number of bricks required is
n=\frac{A_w}{A_b}n=
A
b
A
w
n=\frac{14400}{120}n=
120
14400
n=120n=120
Therefore, Number of bricks are 120.
Hope it's help you
Answer:
Given height of wall needed =2.88m
Width of wall needed =50cm =0.5m
Given length of 1 brick =12cm
Breadth of 1 brick =10cm
Area of 1 brick =12×10=120cm
2
Area of wall needed =2.88×0.5
Area =14.40m
2
Now number of bricks needed =
Areaofbrick
Areaofwall
No. of bricks needed =
120
14.40×10
4
=
120
1440×100
