Your order of 100 2x4 boards (8 ft long) equals 533.33 Board Feet. This is equivalent to approximately 44.4 cubic feet of wood.
Weight Estimate
Assuming standard pine/fir (approx 2-2.5 lbs/BF), this load would weigh between 1067 and 1333 lbs.
Nominal vs Actual
Remember that a "2x4" is the nominal size. The actual dimensions are typically smaller (e.g., a 2x4 is actually 1.5" x 3.5"). Board feet is usually calculated on nominal dimensions.

Inputs:
Size:2x4
Length:8 ft
Count:100
Steps:
- 1.BF per board = (2 * 4 * 8) / 12 = 64 / 12 = 5.33 BF
- 2.Total = 5.33 * 100 = 533 BF
