How much does 100 cubic feet of pea gravel weigh?
You need to tell us how much let’s say a gal. bag weighs first. I happen to have a gallon bag of pea gravel and it weighs almost 12 pounds. Sooo…doing some math (with my husband’s help), we came up with about 9,000 pounds as your total. The density (and, thus, the average weight) of the individual pea-size gravel is only a minor variable to take into account since the average density varies only slightly across the U.S.–according to my son who works for Pioneer Sand & Stone in Phoenix, Arizona.
