Answer 2

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 =

volume of 1brick/volume of wall

no. of bricks=30m^3/1000m^3=30/1000×10^6=30×10^3

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