find the volume of the wall first
dimensions are 10m=1000cm
8m=800cm
6m=600cm
volume is 1000×800×600
=480000000 cubic cm
volume of each brick is 25×20×10
=5000 cubic cm
therefore total number of bricks is 480000000/5000=96000
dimensions are 10m=1000cm
8m=800cm
6m=600cm
volume is 1000×800×600
=480000000 cubic cm
volume of each brick is 25×20×10
=5000 cubic cm
therefore total number of bricks is 480000000/5000=96000
