Answer:
SOLUTION:
Volume of each piece
= lbh=lbh
= 30 \times 20 \times 15=30×20×15
= 9000 {cm}^{3}=9000cm
3
Volume of Wooden Block
= {a}^{3}=a
3
= {3}^{3}=3
3
= 27 {m}^{3}=27m
3
= 27000000 {cm}^{3}=27000000cm
3
Therefore, Number of Pieces
= \frac{27000000}{9000}=
9000
27000000
= 3000 \: pieces=3000pieces

cuboid volume = 30*18*5 = 2700 cm³
no.of cuboid blocks formed = 27000000/2600
= 10000
