answer-
volume of log = 800cm * 500cm *80cm
volume of log = 800*500*80
volume of log = 32000000 cm cube
volume of wooden block = 20cm * 20cm * 20cm
volume of block = 20*20*20
volume of block = 800 cm cube
number of blocks that can be cut = 32000000/800
= 320000/8
= 40000 blocks
hope it helps
have a nice day
