Answer 2

Hi friend,

Here is your answer,
_____________________________________________________________

Number of cubical blocks = Volume of log of wood/Volume of one cube

Volume of log of wood = 800*500*80

Volume of one cube = 20*20*20

Number of blocks = ⁸⁰⁰*⁵⁰⁰*⁸⁰/₂₀*₂₀*₂₀
                             = 4000
