Estimate the amount of rubber mulch (in cubic feet and pounds) needed to cover a specific area at a desired depth.
Rubber mulch is a type of ground cover made from recycled tires. It's known for its durability, excellent shock absorption (making it great for playgrounds), and ability to inhibit weed growth. Unlike wood mulch, it does not decompose over time. It's typically sold in bags by weight (lbs) or volume (cubic feet).
