Depends on the sheet thickness. A general rule of thumb is 900mm total bundle height. So 900-200mm for packaging for 9mm sheets would equal roughly 77 sheets.
Ask the supplier, as quantities vary, especially if on offer.

Usually there are 10 in a bundle.

A 2X6 (dry Douglas fir) weighs 2lbs per foot. Thus a 20ft 2X6 would weigh 40 lbs. Other types of lumber such as pine weighs more and all lumber is heaver when wet or if it has been treated.
1 1/2"x 5 1/2"
2x4, 2x6 and 2x10
For 2×4s of any size, it is 294 pieces of lumber. A "bunk" is a collective quantity for shipped lumber, and each size of lumber has a different quantity for a specific type of wood.. 2x4 = 3 x 7 x 14 (294) 2x6 = 3 x 7 x 9 (189)
Lumber yards and home improvement stores in the U.S. generally stock stud length 2x6's (92-5/8").
A 2X6 is 5 1/2 inches wide. Incidentally it's 1 1/2 inches thick. Pre-WWII lumber was cut at stated dimensions, a 2x4 was actually 2 inches by 4 inches.
A saw mill rough cuts a log into standard sizes of lumber such as 2x4, 2x6, 2x8,etc. The rough cut lumber is cut to the actual measurements of 2" x 4", 2" x 6", 2" x 8", etc. The lumber at this point is very rough so it is run through a planner that smoothes the lumber by removing a small amount of wood on each of its four sides. The actual dimensions of the lumber after being smoothed is 1/2" smaller in both width and thickness so a 2x4 will actually measure 1 1/2" x 3 1/2", a 2x6 is 1 1/2" x 5 1/2", a 2x8 is 1 1/2" x 7 1/2", etc. A 2x6 bought by a consumer at a lumber yard is actually only 1 1/2" or 1.5" thick and 5 1/2" or 5.5" wide. A 1 foot (12") length of 2x6 is (5.5" x 12") 66 square inches. 64 square feet is equivalent to (64 x 12" x 12") 9,216 square inches. So it takes (9,216/66) 139.64 feet of 2 x 6 to cover 64 square feet. Ten 2x6's 14 feet long will cover almost exactly 64 square feet.
