Question

A wall of length 10 m was to be built across an open ground . the height of the wall is 9 m and thickness of the wall is 24 cm .if this wall to be built up with brick whose dimensions are 24cm× 12cm × 8cm ,how many bricks would be required

Answer 1

Given,
Length of wall=10 m=1000 cm
Height of wall=9 m=900 cm
Thickness of the wall=24 cm
Length of one brick=24 cm
Height of one brick=12 cm
Thickness of one brick=8 cm
To find,
Number of bricks required to construct the wall
ATQ,
No. of bricks=Volume of wall÷Volume of one brick
So,
Volume of wall=Length×Breadth×Height
=(1000×900×24) cm³
=21600000 cm³
Now,
Volume of one brick=Length×Breadth×Height
=(24×12×8) cm³
=2304 cm³
Now,
No. of bricks=21600000/2304
=9375 bricks

Hope this helps you!
