You need to provide more information about the fabric, specifically the width of the goods and the direction of the pattern. That's the short and unsatisfying answer. The long answer: IF the pattern on your fabric is able to be run horizontally, and IF the fabric width is at least 69" (most upholstery fabric is 54" wide, and apparel fabric is only 48" wide), your panels will be fairly simple to figure. You can use a full width, turned sideways, and simply count the number of finished panels (9) times the finished panel width (72 inches=6 feet=2 yards). This simple arrangement would therefore require 18 yards of fabric. Also, professional designers always order at least 15% "overage", especially on custom or hard-to-find fabrics, to allow for matching patterns and to insure against coming up short. Fabric colors vary depending on the days they are manufactured, and even the slightest difference in dyes will show up glaringly if you have to go back for more fabric. Unfortunately, I doubt your chosen fabric is made that wide. You will have to make a diagram, showing the direction of the pattern and the number of pieces you'll have to stitch together to make the panel size (don't forget your seam allowances and hem/pocket depths). Fabric can be expensive, and it is not very forgiving of cutting mistakes. Another thought: the vendor of the fabric should provide a measuring and estimating service. This may or may not be completely reliable (they are trying to sell as much fabric as they can), but it can confirm your own estimations. A few tips: never place a seam down the center of a panel; instead, split one piece and sew to both sides of a full width centered on the panel. If your panels are to be used as window dressings, the daylight will almost always show every seam you sew. Never use silk in window dressings without protecting it from sunlight, which will deteriorate all your hard work. Use blackout lining or a UV-protecting coating. Silk will also deteriorate in saltwater atmospheres. Don't forget to check out your local library for some of the wonderful how-to books on crafting beautiful window fashions. Good luck!
It depends on how full you want the curtains to be. You also have to consider if the fabric has a printed pattern, which direction you want them to lay.
Most fabrics are 40 inches wide . . . so for the sake of argument, you want to run the fabric from width to width. Double ( approximately ) the width, for a nice fullness.
The length should extend a few inches beyond the length of the window, accounting for about a 4 inch hem, and seam allowance . . . and the rod pocket,
and any stand up ruffle you might want.
So you are looking at approximately 3 yards of fabric per curtain, or 6 yards total.
To cover it, about 3 and 1/2. Get four.
Nine yards is 324 inches. (36 inches per yard).
1,200 inches 33.33 yards
feet = kinda meters/yards = yes inches/cm = no
The answer depends on the width of the fabric which has not bee mentioned. There are a number of standard widths.
yards and miles i doubt the building is over 2 miles high but if it is use miles. if not, yards
The US quarter is 0.069 inches thick so stacking 6 million quarters would be 6 million * 0.069 inches or 414,000 inches. 1 yard = 36 inches. So divide 414,000 inches by 36 to get yards = 11,500 yards (which is about 6.5 miles!)
Tyoically fires a bullet at about 2830 feet per second. When zeroed at 250 yards, will be 0.4 inches high at 25 yds, 4.1 inches high at 100 yds, and 6.1 inches low at 300 yards.
2 yards of paper
7.34 cu yds.
Sorry the first answer was in square yds. Cubic yards would be 0.308639
Volume = Height x Length x Width 91 inches x 112 inches x 60 inches = 611,520 cubic inches. This large a volume is usually converted to cubic feet or cubic yards. 611520 cubic inches = 611520/1728 cubic feet = 353.89 cubic feet 611520 cubic inches = 611520/46656 cubic yards = 13.1 cubic yards
