Side of the cubical block=20cm
Volume of the block=side^3
=20^3
=20*20*20
=8000 cm^3
Length of the log of wood=8cm
Breadth=5cm
Height=80cm
Volume of the log of wood=L*B*H
=8*5*80
=3200cm^3
Number of cubical blocks can be cut,
=Volume of the blocks/Volume of the log of wood.
=8000/3200
=2.5 blocks
Hope it helped you............
