Answers
How many bricks of size 25cm into 15cm into 6cm are required to make a wall 5cm long, 2m high and 50cm thick, if 10% place is occupied by cement?
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
Answer:
Step-by-step explanation:
Dimension of brick are =20cm×10cm×5cm
volume of 1 brick =20×10×5=1000cm
3
Dimension of wall =10m×15m×0.2m
volume of wall =10×15×0.2=30m
3
now no. of brick requried to make wall =
volumeof1brick
volumeofwall
no. of bricks =
1000m

[no. of bricks =30,000 bricks.]
