31 Studs not counting corners
the wall thickness of sch 40 - 500mm dia pipe is 15mm or 16mm.
800 C feet
The difference between schedule 40 and 80 pvc is the wall thickness and schedule 80 is thicker then schedule 40 so the higher the schedule number the thicker the wall of the pipe thus can hold more pressure.

The gauge of the pipe is the wall thickness. It is easier to say Schedule 40 pipe than .180 inch wall thickness. This is the SCH 40 wall thickness for a standard 12" pipe and the actual gauge thickness will vary based on pipe size and material. The larger the Schedule number, the thicker the pipe wall thickness. Pipe Schedule is also expressed in Std., X-Stg., and XX-Stg. since some thicknesses are more common than others.
To calculate the board feet in a 40-foot wall, you need to determine the height and thickness of the wall. Board feet is calculated using the formula: (width in inches × height in inches × length in feet) / 12. Assuming a standard wall height of 8 feet and using 2x4 lumber (which is actually 1.5 inches by 3.5 inches), the calculation would be: (3.5 × 96 × 40) / 12, resulting in approximately 120 board feet for a single layer of studs.
40 foot = 40 feet
If you drywall on 16" on-centre studs, with sheet length perpendicular to the studs, and screw the two outside length edges at 6" spacing (as it should be) and the two interior studs at 12" spacing, the answer is 48 drywall screws per 4'x8' sheet.
40 x 50 = 2,000 (sq ft).

It is not possible to answer this question since a 40 foot octagon could be extremely long.

12 feet X 40 feet = 480 square feet.
