12 in = 1 ft
⇒ 60 ft x 100 ft x 4 in = 60 ft x 100 ft x (1 ÷ 12) ft
= 500 cu ft
Close, but you left out the 4 in (1/12) above. You had it on the left, but you left it out on the right. That makes the correct answer 2000 cu ft.
enough to cover it
I need to know how thick the layer of gravel is meant to be.
I think you mean 6 inches thick, not 6 feet thick. You would need 200 cubic feet, or 7.4 cubic yards.
0.69444 cubic yard (rounded)
Convert the thickness to meters, then multiply base x area. Answer is in cubic meters. Alternately, you can also convert everything to decimeters first, or to centimeters.
You need to specify how thick you want the top soil to be
enough to cover it
You will need about 3.7 cubic yards (around 4.75 tons) of gravel.
you need heavy jackets warm boots maybe muklucks and thick gloves and a face cover

For being a farmer there is no need to have your own land
