Answer:
4000 wooden cubical blocks can be cut from the log.
Step-by-step explanation:
Edge of cubical blocks of wood = 20 cm
Length of log of wood (l) = 8 m = 800 cm
Breadth of log of wood (b) = 5 m = 500 cm
Height of log of wood (h) = 80 cm
No. of wooden cubical blocks = Volume of log of wood/Volume of wooden cubical blocks
= l × b × h/(edge)³
= 800 × 500 × 80/20 × 20 × 20
= 500 × 8
= 4000 blocks
