for example if any steel take 1.0 meter cutting length
density= weight / volume
density of steel is 7850kg/m3
volume of steel = areaX length=3.14xD2/4*1.0
weight of steel for 1m is= density X volume
= 3.14D2x1000*7850/1000*1000*1000
=D2/162 (square of D/162)
where D is the dia of bar in mm
for 45degrres =cutting length-1 * dia of bar* no of bends
for 90 degrees= cutting length-2 * dia of bar*no of bends
