15 inches = 1.25 feet
Volume of the bed = (4 x 8 x 1.25) = 40 cubic feet
6,400 ft3
806.66 Cubic Yards
The formula for the volume is length * height * depth (or width) = 33 =3*3*3 = 27 cubic feet, but the answer to the question is 0; there's no dirt in a hole... We are not digging a hole here; we are building a mini-mastaba that is 1 foot deep above the original ground level. 48 cubic feet of dirt is required which equals 48/27 = 1.78 cubic yards of dirt.
10*13*3 = 390 cubic inches.
24 x 8/12 = 16 cubic feet.

If the raised garden has dimensions of 5 x 5 x 1 then it requires 25 cubic feet of dirt to fill it.
1,728 cubic inches of it
10-1/2 cubic yards
10*13*3 = 390 cubic inches.
The total volume is 1568 cubic inches, so 1000 cubic inches of dirt will fill about 2/3 of the container
You will need 1500 cubic feet.
24 x 8/12 = 16 cubic feet.
A little over one cubic feet of dirt. But, you would want to mix this with compost or potting soil. This will provide nutrients to the soil. You may want to add mulch after planting to keep the weeds down.
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
