Answer:
First You have to find out Sq. Mtr of the total plywood with help of below given table
8 Ft = 2.44 Mtr
7Ft = 1.22 Mtr
6Ft = 1.84 Mtr
4Ft = 1.22 Mtr
3Ft = 0.92 Mtr
2.5 Ft = 0.76 Mtr
after that divide the thickness by 4
Then Multiply Total Square Mtr by the result will give you Notional Area
Then Multiply the Notional Area by 3 = Weight In Kg.
Like Wise Given Below
Suppose we try to find out the weight of 12 MM HARDWOOD PLYWOOD 8X4. It'll be like
Height Width Sq. Mtr
2.44 X 1.22 = 2.9768
Sq. Mtr Thickness Constant Notional Area
2.9768 X (12 / 4) = 8.9304
Notional Area Constant Weight
8.9304 X 3 = 26.791 Kg
