## Unequal length L section beam Calculation Here, we will have to know the outer and inner edge dimensions.
The volume of the unequal L section = cross-sectional area x Length

Where X1 is outer edge width, Y1 is outer edge height and x2 is inner edge width, y2 is inner edge height.
Let us consider a 1 m long unequal L section of outer edge width 60 mm = 0.060 m, outer edge height = 30 mm =  0.030 m  and inner edge width 55 mm = 0.055 m , inner edge height = 25 mm = 0.025 m.
So, Volume of the L section = [ ( 0.060 × 0.030 ) – ( 0.055 × 0.025 ) ] × 1 = 0.000425 m3

Hence, mass of the L section = density × volume = 7900 × 0.000425 = 3.3575 kg
In this way, we can calculate the weight of an unequal-length L – section beam

## Equal length L section beam Calculation Here, we will have to know the outer and inner edge dimensions.
Volume of the L section = cross-sectional area × Length
V= A x L = (( X1 × Y1 ) – (x2 × y2 )) × L
Where X1 is outer edge width, Y1 is outer edge height and x2 is inner edge width, y2 is inner edge height.
Let us consider a 1 m long L section of outer edge width 30mm = 0.030m, outer edge height = 30 mm =  0.030 m  and inner edge width 25 mm = 0.025 m , inner edge height = 25 mm = 0.025 m.
So, Volume of the L section = [ (0.030 × 0.030) – (0.025 × 0.025) ] × 1 = 0.000275 m3
Hence, mass of the L section = density × volume = 7900 × 0.000275 = 2.1725 kg
By using this formula we can calculate the mass of equal length L – section beam of different dimensions.
