Question

how many wooden cubical blocks of edge 20 CM can be cut from a log of wood of size 8m by 5m by 80cm assuming there is no wastage​

Answer 1

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
