Question: how many square feet does a yard of pea gravel cover?
Answer: Divide the 0.167 cubic feet by 27 cubic feet per yard to get 161.7 square feet that can be covered by 1 full yard of the pea gravel. In other words, 1 cubic yard will spread out to a rectangle that measures 10 feet wide by approximately 16 feet long and 2 inches deep.
