B calculati the B005 data- at 20°C of a waste BOD water sample вол bottle capacity = 300 me following SEED CONTROL vol. of Seed added = Doi of Seed + DW = DO of seed + DW = 4.8 ome 8.2mg le mgle TEST SAMPLE vol- of seed added = 2ml vol of sample added = 30 me Doi of SS + D.W + Sample = Dof of S.St D.W + sample= 6.1mg Il = 3.2 mgle

Pls do both the parts otherwsie skip I'll rate with 2 ids positively if u follow what I have said

2. A wooden pole- untreated, will last for 10 years under a certain soil condition,costs P1.2M.
