Question

a brick measures 30 centimetre into 10 cm into 7.5 centimetres how many bricks will be required for a wall 30meter long 2 metre high and 3upon 4meter thick​

Answer 1

Step-by-step explanation:

30m =3000 cm ,2m=200 cm ,3/4=75 cm

volume of wall=3000*200*75

volume of bricks=30*10*7.5

volume of wall = no of bricks* Volume of bricks

now,

3000*200*75=n*30*10*7.5

.: n=20000

hence required bricks=20000
