Question: how many square feet does a 50 lb bag of gravel cover?
Answer: A 50# bag of pea gravel is about 0.5 cu. ft. so if you were planning on a 2″ thick cover it would cover 3 square feet, a more usual 4″ thick cover would cover 1.5 square feet. there are on line calculators just search “how many bags of gravel do I need” and you will have lots of hits…
