Identifying Fat Sac Size

[mjr119]

What's the best way to determine the weight of a fat sac? I just got 10 launch pad fat sacs, and I dont know which ones they are. They are all pretty old.

should have a seriel number on them that does size, but I have filled with air from shop vac and just measured l x w x h

If they have a label on them with a serial number, then there's going to be last 6 digits of that number that will be the dimensions. For example, you'll see 101670 that says it's 10x16x70 inches.

Or on this one, 102054 = 10x20x54" which corresponds to 390 pounds of water for that volume. I've found some online volume calculators where you can enter dimensions in inches and select water and it'll give you the weight in pounds. But I can't seem to find the one I used before. but obviously, if you have dimensions, you can figure out volume in Cubic Inches, then convert cubic inches to gallons and multiply times the 8.33 pounds per gallon. Or just get the cubic inches LxWxH and multiply that times the weight of water per cubic inch, which is 0.036127

Start taking some rough measurements and compute the volume in Cubic inches of the bags...
