One garden bed measures 8ft long, 4ft wide and 1ft high so to find the cubic feet needed, 8 * 4 * 1 = 32 cubic feet of soil needed. Both beds are the same size so she needs 2 * 32 = 64 cubic feet of soil. Every bag has 4 cubic feet of soil and she needs 64 cubic feet so 64 / 4 = 16 bags needed. So the answer is 16.
