How to calculate the weight of titanium hexagonal titanium rod?

Hexagonal titanium rod is different from titanium round rod. The weight can be calculated according to the cylindrical mass calculation formula. The following is the weight calculation formula of hexagonal titanium rod calculated based on the weight formula of hexagonal steel rod:
1. Hexagonal titanium rod weight calculation formula

W = 0.0039 × S²

W represents the theoretical weight in kg/m; d is the distance between opposite sides in mm.
