Answer 1

Answer:

n=2800

Step-by-step explanation:

dimensions of wooden plank: 2m×25cm×8cm

l=2×100cm=200cm

b=25cm

h=8cm

dimensions of wooden block:

L=70m =7000cm

B=5m=500cm

H=32cm

volume of wooden block=n×volume of plank

7000×500×32=n×200×25×8

112000000=n×40000

n=112000000/40000

n=2800.

here n is no.of planks.....
