When decorating with wood-grain paper, the size of the surface of the decorated object is different, and the amount of wood-grain paper is also different. For example, when decorating a room with wood grain paper, you can calculate it like this:
(1) For example, if the width of the bedroom is 5m and the length is 3m, then the perimeter is 16m=(5+3)*2;
(2) The total height of the wall with wallpaper = the length of the room-the width of the door-the width of the window, that is, 13.3m=16m-1.8m-0.9m, under normal circumstances, the height of the wall is generally between 2.3m-2.9m ;
(3) The width of each roll of wood-grained paper on the wall: Taking the wallpaper width of 0.45m as an example, one roll can cut 3 pieces, and the wall width used for one roll is 0.45*3=1.35m;
(4) The number of wallpaper rolls required: the number of rolls = the width of the bedroom to be covered with wallpaper / the width of the wall that can be covered per roll, that is, 13.3/1.35=9.9.
