yards is a unit of length, not of area.
The 'square feet' of area that it covers is 1,620/(depth of the mulch, in inches)
10 sqare feet is an area so it covers 10 square feet.
10 sqare feet is an area so it covers 10 square feet.
225 feet.
Six feet in 2 yards.
880 yards = 2640 feet.
First work out the area in square feet. To do this multiply the length by the width. 9 feet by 12 feet equals 108 square feet. Then convert square feet to square yards. There are 9 square feet in 1 square yard. So divide 108 by 9. The answer is 12 square yards.
That's going to depend on how deep or shallow you spread it. If you spread it one foot deep, it covers an area of 2 square feet. If you spread it one inch deep, it covers an area of 24 square feet.
1.6 yards = 5 feet.
155 feet = about 51.7 (51.6666667) yards.
450 feet - you multiply yards by 3.
30 yards=90 feet
