Question

a bick measure 15cm in length,8 cm in breadth and 5cm in height how many bricks will be used to make a wall of length 15 cm breadth 10 m and height 8 metres? ​

Answer 1

Answer:

volume of a bick=(l×b×h)

=(15×8×5) cc

=600 cc

In the wall,

l= 15 cm

b=10 m=1000 cm

h=8m =800 cm

Then the volume= (l×b×h)

=(15×1000×800) cc

=12000000 cc

So, the numbers of used bricks will be= 12000000/600

=20000
