Answer 1

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

Answer 2

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.

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

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

Number of bricks required=1600
