Answer:
Size of wall : ( CONVERT IN CM)
5 cm long
2 m = 200 cm high
50 cm thick
therefore: 5*200*50 equals 50,000 cm3
Size of brick:
25*15*6 equals 2250 cm 3
divide 50,000 by 2250 =22.22 blocks
take 90% of 22.22 blocks equals 19.98 block
so it means 20 blocks will be required for making a wall 5 cm long, 2 m high and 50 cm thick including 10% of cement
