40x5
The GCF is 8x^3
40x1=40 40x2=80 40x3=120 40x4=160 40x5=200 40x6=240 40x7=280 40x8=320 40x9=360 40x10=400
It goes: 170/40 = 4 with a remainder of 10
Area in sq. millimetre divided by 127 is the wt. of steel in Kilo Gram (Kg.) per metre length. e.g. 40mm wide flat with thickness 5mm = 40x5 =200/127 = 1.57 kg. 12mm Round bar will have are of 113.14 sq. mm divided by 127 the wt. will be by 0.89 kg. per. mt. length. by H.K. Dua
