To find the total length we justadd the llength of the vBulletin peices together 9 +5.59 + 16 . 8 = 31.39
The total length is 31.39
12(16x+2) that's the answer
Area of the cross section (Trapezium) :
1/2 (6 + 11) x 3 = 25.5 cm²
Volume = area x height = 25.5 x 3 = 76.5 cm³
If you want to work out the force then F=MA, therefore 43*8.6=369.8 Newtons
