First, convert all measurements to feet to ensure consistency: length = 20 ft, width = 2 ft, thickness = 6 inches = 0.5 ft. Calculate the volume (V) of the beam using V = LWH = 20 ft * 2 ft * 0.5 ft = 20 cubic feet. Then, calculate the density (D) using D = W / V = 150 lb / 20 cubic ft = 7.5 pounds per cubic ft.
