12 cubic feet. 8 x 2 x .75
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
find the area of it 320 feet squared
To find out how much dirt is needed to fill a 12x18x36 planter box, first convert the dimensions into the same unit, if necessary. The volume can be calculated by multiplying the length, width, and height: (12 \text{ inches} \times 18 \text{ inches} \times 36 \text{ inches} = 7,776 \text{ cubic inches}). To convert this to cubic feet, divide by 1,728 (since there are 1,728 cubic inches in a cubic foot), resulting in approximately 4.5 cubic feet of dirt needed to fill the planter box.

This question is about a cubed area. First convert the inches to feet--18 inches is 1.5 feet. Then multiply all three numbers by each other. 15*12*1.5 is 270. You will need 270 cubed feet of dirt to fill the area.
hmm that's a tough one maybe 24' by 2' by 10 inches worth of dirt
The answer will depend on the depth to which the area is covered.
To calculate the amount of fill dirt needed for a berm that is 4 feet high and 200 feet long, you also need to know the width of the berm. Assuming a width of, for example, 3 feet, the volume can be calculated using the formula: Volume = Length × Width × Height. In this case, it would be 200 feet × 3 feet × 4 feet = 2,400 cubic feet of fill dirt needed. Adjust the width accordingly for a different volume.

This problem gets easy quickly if you put everything in the same units. When you see 4 inches, think of one third of a foot. Fifteen feet times a third of a foot gives five square feet. Multiply 5 by 20, 100 cubic feet. If you are going to get the dirt by digging it from compacted soil, get 100 cubic feet. If you are getting loose dirt, better get 120 cubic feet - it will settle !
3ft x 3ft x 1ft = 9 cubic feet of dirt will be needed.
