Number of bars in 1.00 mt area
8 mm dia bar = 1/0.15 = 6.67
Say = 7 no's
weight of steel = 7*0.39 = 2.73 kg

For 10 mm steel number of bars in 1.00 mt area
No's = 8 mm dia steel weight / unit weight of 10 mm steel
= 2.73 /.62
no's = 4.4
Specing = area / no's bars
= 1/4 .4= 0.228
For 10 mm steel specing = 200 mm c/c
