It depends on the height and shape of the building. Example: a 40x50 building with 10 foot walls = 1800 sq feet. 20x100 building with 15 foot walls 3600 sq feet
10 x 12 = 120 square feet on the floor 10 x 12 = 120 square feet on the ceiling (10 x height) on each of two of the walls (12 x height) on each of the other two walls Total square feet in the room = [ 240 + (44 x height) ] square feet
The floor and ceiling are each 20 square feet. In order to know the area of the walls, we would also need to know the height of the ceiling.
The floor and ceiling are each 72 square feet.In order to know the area of the walls, we would need to know the height of the ceiling.
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
84 square yards
In order to calculate that, we also need to know the length of the room.

14.) A room is 24 feet long, 18 feet wide, and 9 feet high. How many square yards of wallpaper are needed to paper the four walls of the room?
12 x 4 = 48 square metres.
Each wall is (8 x 12) = 96 square feet.Two walls = (2 x 96) = 192 square feet of wallpaper.
2 walls are 18 x 9 and 2 walls are 24 x 9 so not counting doors and windows it is 2x18x9 + 2x24x9 = 756 sq ft

Most modern emulsion paints should cover any type of wallpaper. The only problem with this is that the weight of paint and water content may 'peel or sag' the original paper on the walls. This will depend on the type of paper etc. My suggestion is, don't cheat, strip the old wallpaper off and then decide whether to paint or paper.
AnswerYou can Hang wallpaper over wallpaper but it tends to not hold to the walls as well as hanging in on a bare surface. However, if you must, first paint over the old wallpaper with an oil-based paint. If you use acrylic the paper may bubble up. To make a perfectly smooth surface, mud the wall with drywall mud and then smooth by sanding. Finally, paint it again and then hang the paper. Most of the time it is easier just to remove the old paper. See the external link for more information.
You can't paint your walls. You need to buy wallpaper from the YoDepot.
2 x (length + width) x height = 2 x (8 yd + 6 yd) x 3 yd = 2 x 14 yd x 3 yd = 84 square yards
