Question

Number of bricks of size 20x10x10 cm required for constructing a partition wall 10m long 1m high and 10cm thick is

Answer 1

change MTR in CM to convert

Answer 2

Answer:

number of bricks is 500.we convert the whole dimension in cm(centimeter) from m(meter).for the solution we divide the volume of wall and volume of brick size.

Step-by-step explanation:

volume of wall = $10m*1m*10cm$

volume of brick = $20cm*10cm*10cm$

most of the values in cm.so we should convert m(meter) into cm(centimeter).

$1m=100cm$

$10m=100*10\\10m=1000cm$

volume of wall = $1000cm*100cm*10cm$

now calculate the number of bricks.

number of bricks = volume of wall/volume of brick

                             $=1000*100*10/20*10*10\\=1000000/2000\\=500$
