Question

a wall 12m long 9m high and 10m wide has to be built from the bricks 40cm long 6cm wide and 2.5cm high each how many bricks will be required to make this wall​

Answer 1

Step-by-step explanation:

length of the wall = 12m

breadth of the wall=10m

height of the wall =9m

Volume = 12*10*9

=1080m3

or, 108000cm3

length of brick =40cm

breadth of the brick =6cm

width of the brick =2.5cm

volume=40*6*2.5

=600cm3

now dividing the two volumes =108000/600

=180

Hence, 180 bricks will be required
