    4 ft x 1 ft = 4 sq. ft. Multiply that by how deep you want the dirt to be. Let's say 2 ft. That would be 4 x 2 which would equal 8 cubic feet.

    For 3 beds like that, you will need 8 cubic feet x 3 beds which equals 24 cubic feet of soil.

    Calculate the area of the beds. Total length x width x depth in feet. Divide that by 9 to convert cu feet to cubic yards.

  • It also depends on how dense your garden soil is, if you're buying some or simply moving some? I've built quite a few raised beds in the past and the soil will always settle once it's cultivated and watered. You may also want to consider adding compost as you're establishing those and possibly manure to get some nutrients in the soil right away.

    Also consider how DEEP you want to plant your plants. Some plants need deeper soil. Always put drainage in bottom of raised beds to prevent rotting.

    Multiply the width x the length x the height. That will give you cubic feet. 3 x 4 =12, times one foot deep = 12. If it were 1 1/2 feet deep, 12 x 1.5 = 18 cubic feet.
