conversations.value: Can you break down the solution for me for this math problem: Bob needs to buy potting soil to fill the raised beds in his vegetable garden. He has 10 raised beds, and each bed is 2 feet wide by 8 feet long by 2 feet tall. Each bag of potting soil holds 2 cubic feet of soil and costs $12. How much will the potting soil cost him?
conversations.from: assistant
conversations.value: Each bed is 2 feet wide by 8 feet long by 2 feet high, so they each hold 2 * 8 * 2 = 32 cubic feet of dirt.
  He has 10 beds, so he will need 10 * 32 = 320 cubic feet of dirt.
  Each bag of soil is 0.75 cubic feet, so Bob will need 320 / 2 = 160 bags of soil.
  Each bag is $12, so all the soil will cost him $12 * 160 = $1920.
