Depends entirely on how good your boarding and taping is.
That would be almost impossible to determine because there is no way of knowing the different thicknesses that will actually fill the wall surface.
You will need at least 14 sheets, depending on shape and height of wall.
I use about five pounds per 10 -12 sheets.
A 10 X 10 area or 100 square feet.
Around 350 square feet

One piece = 4 x 12 = 48 square feet 665 pieces cover (665 x 48) = 31,920 square feet 3,5462/3 square yards 0.001145 square mile (rounded).
1 gallon of paint to cover about 350 square feet You need slightly more than a gallon if the walls are unpainted drywall, which absorbs more of the paint
56 sq feet
4 x 10 is 40 square feet, so two would do it.
If a good job is made of the placing, one large bucket or box ( 5 gal size) should do it.
40 feet x 25 feet = 1,000 square feet.
To find square feet simply multiply length times width. Thus: 11' X 12' =132 square feet. If you needed to figure the amount of sheet rock to cover four walls in one room and the room is 11' X 12' with 8' ceiling height your equation would look like this: 11 x 12 x 4= 528 square feet Now divide the total square feet (528) by the amount of coverage one sheet of drywall offers. ie; one 4 x 8 sheet of drywall covers 32 square feet of space. 528/32=16.5 You would need 16.5 sheets to cover all the wall space with 4' x 8' sheets of drywall.
