CALCULATING NUMBER OF BAGS
We recommend determining the height and length of your project first. A filled bag will be approximately 2 feet long, and 4 inches tall. From there, calculate the number of bags that you need and order the corresponding kit size.
HEIGHT
of feet / .4 ft = 
of Bags High
LENGTH
of feet / 2 ft = of Bags Long
TOTAL NUMBER OF BAGS
of Bags High x of Bags Long = of Bags
