6,400 ft3
cylinder 18 feet diameter x 1.5 feet deep volume = 381 cubic feet
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
1.963 cubic feet
24 x 8/12 = 16 cubic feet.
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.
8 cubic feet.

There is no dirt in a hole that is 3 feet deep and six inches in diameter.
A hole 40 inches deep by 12 inches wide has a volume of: 2.62 cubic feet.
1.963 cubic feet
You will need 1500 cubic feet.
24 x 8/12 = 16 cubic feet.
35 cubic feet

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 !
16 sq ft*0.5 ft = 8 cubic feet.
