Question

How many bricks will be required for constructing a wall which is 16 metre long 3 metre high and 22.5 cm thick if each brick measures 25 cm x11.25 cm x 6 cm​

Answer 1

Answer:

Step-by-step explanation:

Dimention of Wall;

l=8m=800cm

h=6m=600cm

b=22.5cm

volume of the wall =lbh=800×600×22.5

=10800000cm3

Dimention of brick;

l=25cm

b=11.25cm

h=6cm

volume of brick =lbh

=25×11.25×6

=1687.5cm3

therefore number of bricks=volume of wall/volume of 1 brick

=1687.510800000​

=6400 bricks

Therefore number of bricks are 6400.

Answer 2

Hey mate,

Question :-

How many bricks will be required for constructing a wall which is 16 metre long 3 metre high and 22.5 cm thick if each brick measures 25 cm x11.25 cm x 6 cm .

Answer :-

$\boxed{ \green{ \huge{6400}}}$

Step by step Explanation :-

Length of the wall = 16 m = 16 x 100 cm = 1600 cm

Height of the wall = 3 m = 3 x 100 cm = 300 cm

Breadth of the wall = 22.5 cm

Volume of the wall = 1600 x 300 x 22.5 cm3 = 1,08,00,000 cm3

Volume of one brick = 25 x 11.25 x 6 cm3 = 1687.5 cm3

Number of bricks required to construct the wall = $\frac{Volume /: of :/ the :/ wall}{Volume of the brick}$ = $\frac{1,08,00,000}{1687.5}$ = 6400

Hope it helps...
