convert everything to meters suyash

radar · Answer

Note that the bricks are 24 cm thick and you will need only one layer.
also not that the side area of the wall is 10m by 4m or 40 square meter.  
Next calculate the side area of the brick which would be: (in square meters) .10 X .08 =.008 sq meter.  Number of bricks need (neglecting mortar thickness between bricks) would be 40/.008=5000 bricks.

Volume of the wall:
10*.24*4 = 40*.24 = 9.6 m^3

radar · Answer

Apparently they considered the mortar thickness (width of joint where mortar is placed to hold the bricks together.

bahrom7893 · Answer

Volume of each brick:
.24*.1*.08 = 0.00192

bahrom7893 · Answer

Divide the volume of the wall by the volume of one brick:
9.6m^3/0.00192m^3 = 5000 bricks
