Assuming by "yard" you mean a "builder's" yard = 1 cubic yard:
1 yd = 3 ft
1 cu yd = 1 yd x 1 yd x 1 yd = 3 ft x 3 ft x 3 ft = 27 cu ft.
1ft x 200 ft x 200 ft = 40000 cu ft
→ 40000 cu ft = 40000 ÷ 27 cu yd = 1481 13/27 cu yd ≈ 1481.5 cu yd.
6.67 cubic yards
200*200 = 40000 sq feet. Simplicity itself!
1.851852 cubic yards
35/9 cubic yards for every foot deep.
1 foot = 1/3 yard(440 x 1/3) = 146 and 2/3 cubic yards
You need 82/3 [cubic] yards for every foot deep that it has to be.
.33333333 is how many yards is a foot.
3200 square foot equals how many yards
62/3 cubic yards for every 1-foot deep. 5 cubic yards for every 9-inches deep. 31/3 cubic yards for every 6-inches deep. 5/9 cubic yard for every 1-inch deep.
1 metre = 3.28084 foot 200 metre = (200 x 3.28084) = 656.168 foot
I think 17 or maybe 38
2.37 cubic yards.
