My theory is that that size fits the most bales of boards into standard containers used on container ships, is this true?
Each board has area of (4 x 8) = 32 square feet.Number of boards = (400 / 32) = 12.5 boards
Drywall is not packed on palletes. It comes as a 'lift' of 50, 60, 80 or 100. (depending on size of boards) - A lift of standard 1/2 inch 4 x 8 boards is 100 boards and weighs approximately 5,400 pounds.
The thickness does not enter into the calculation (400)/(4x32) = 100/32 = 25/8 = 3 and 1/8 No one would sell you 3 and 1/8 boards, hence buy 4 boards
4' x 8' = 32'224' x 32' = 768'2768 / 32 = 24 boards.
4 and 8 thousandths (4.008) in standard form is 4.008 × 100
That would depend on the size of the plywood pieces that you are using. You have not specified that. Assuming the area is square, rectangle ; Based on industry standard sizes (8 x 4 ft imperial) then its 31.25 boards. Calculation 1000 square feet to be covered. One 8 x 4 board is 32 sq ft 1000 / 32 = 31.25 boards If 6 x 3 boards are used (again industry standards imperial) then its 55. 55 boards
It is 8 3/4.

The mean is 12 and each observation is 8 units away from 12.
