The formula I use is 15 tons = about 12 yards.
1.851852 cubic yards
15 yards minus 7 yards 2 feet equals 7 yards 1 foot. Therefore, 15 yards minus 7 yards 1 foot equals 7 yards 2 feet.
15 of them because 15 feet = 5 yards
Well 3 yards are in 1 foot so its 5 yards by 5 yards. So 5yds^2.
15X15X.33(4/12 there is 4 inches in a foot therefor 4" is .33 of a foot) equals 74.25 cf of concrete divide by 27 (three demensional object for yards) 2.75 Cubic Yards. if you try to order .75 cubic yards of concrete you will be laughed at, just order 3 cubic yards and make a entrance path. good luck.
18 inches
The formula I use is 15 tons = about 12 yards.
3 feet = 1 yard 45 feet = 15 yards
How deep? 1 inch will take .7 yards
This area requires 3.7 cubic yards.
15 cubic yards
15 cubic yards
1.851852 cubic yards
35 square yards
14.8 cubic yards will work but round to 15 to be sure.
15 yards minus 7 yards 2 feet equals 7 yards 1 foot. Therefore, 15 yards minus 7 yards 1 foot equals 7 yards 2 feet.
