The 'square feet' of area that it covers is 1,620/(depth of the mulch, in inches)
20 feet x 20 ft x .3333 ft = 133.33 cubic feet / 27 cubic feet per yard = 4.94 cubic yards
I think you mean "How much area will 4 yards of concrete cover?". It depends on the slab thickness and whether or not anything significant is embedded (a lot of rebar, conduit, etc.). If working in feet, measure the width length and depth, multiply these numbers then divide the result by 27 to calculate the volume in cubic yards. A slab 9' 6" by 10' 4" by 6" thick translates to 9.5x10.3x.5 (48.93) /27 = 1.8 yards. Since you already have the volume, you will need to play with some of the dimensions to find something that works.
5 yards = 15 feet.
5 ft is less than 2 yards because 2 yards is 6 ft.
25 square yards = 225 square feet.

90 mph = 220 yards in 5 seconds.
5 ft*7ft = 5/3 yards*7/3 yards = 35/9 square yards = 3.88... sq yards.
1.6 yards = 5 feet.
5 yards is approx 3.82 cubic metres.
Well 3 yards are in 1 foot so its 5 yards by 5 yards. So 5yds^2.
5 yards exactly.
5 yards
the answer is 40 square yards
You need to know how much area you are covering and how thick you want the mulch to be. Roughly 3 inches thick is good enough. That is 3/12 = 0.25 feet thick Take area in square feet times thickness in feet, which gives a volume in cubic feet, then divide by 27 to covert to cubic yards For example, if you want to mulch an an area that is 75 feet long and 5 feet wide, the volume is 75 x 5 x .25 = 93.75 cu ft 93.75/27 = 3.5 yards (3 and 1/2 yards)
15 feet in 5 yards. A yard is 3 feet long.
