The same formula will be applied here to calculate.
Volume = cross-sectional area x Length
To calculate the cross-sectional area of the hexagonal rod, we first need to know the side length of the hexagonal rod.
Area= (3√(3 ))/2 S2
Where S = side length of the hexagonal rod.
Let us consider a 1 m long hexagonal rod of side length, S = 10 mm = 0.010m
So, volume of the hexagonal rod = V = (3√(3 ))/2 x (0.010)2 x 1=0.0002598 m3
Hence, mass of hexagonal rod = density x volume = 7900 x 0.0002598 = 2.0524 kg.
By using this formula we can calculate the mass of hexagonal rods of different dimensions.
