Abby is building 2 raised beds to grow vegetables. The beds are both 8 feet long, 4 feet wide and 1 foot high. Each bag of soil has 4 cubic feet. How many bags of soil will she need?
Reason slowly and give your answer.
16
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.

.

Therefore, the answer is 16
