Read All Questions & AnswersHow many bags do I need for a 3 ft x 22 ft walkway (3" depth)?

Per product description covers 6 sq ft at 1" depth. So yours is 3' x22'=66 square feet /6 square feet = 11 bags AND since you want 3" deep would take 11 (for 1" depth) x 3 depth you want would be 33 bags needed.
