10*13*3 = 390 cubic inches.
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
108 cubic feet.
16 sq ft*0.5 ft = 8 cubic feet.

16 sq ft*0.5 ft = 8 cubic feet.
The total volume is 1568 cubic inches, so 1000 cubic inches of dirt will fill about 2/3 of the container
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.
cylinder 18 feet diameter x 1.5 feet deep volume = 381 cubic feet
2.37 cubic yard
No. - Fill dirt is usually junk, often from demolition.
