Answer:
1600 no.of bricks
Step-by-step explanation:
bricks
l=18cm=0.18m
b=10cm=0.1m
h=8cm=0.08m
area=0.18*0.1*0.08m^2
=0.00144m^2
wall
l=12m
b=8cm=0.08m
h=2.4m
area=12*0.08*2.4
=2.304m^2
no.of bricks=2.304/0.00144
=1600
Question
How many bricks of length=18cm,breadth=10cm,height =8cm will be needed to build a wall of length =12m ,thickness =8cm and height 2.4m ?
Given
Length of brick =18cm
breadth of brick =10cm
height of brick =8cm
length of wall=12m(1200cm)
breadth of wall=8cm
height of wall=2.4m(240cm)
To Find
Number of bricks needed to build a wall.
Length of brick=18cm
breadth of brick=10cm
height of brick=8cm
Volume of brick =Length×breadth×height
Volume of brick=18×10×8
Volume of brick=1440cm³
length of wall=12m(1200cm)
breadth of wall=8cm
height of wall=2.4m(240cm)
Volume of wall =length ×breadth×height
Volume of wall=1200×8×240
volume of wall=2304000cm³
The number of bricks required to build a wall=Volume of wall ÷ volume of brick
Number of bricks required=2304000/1440
