Depends on the width of material and what the 2 x 21 is in
Assuming you mean 2 x 21 inches (compared to 2 x 21 yards) and your material is 42 inches wide
Then you can get 2 pieces per 2 inches so you need a length of material 2 x 10 = 20 inches which is 2/3rds of a yard
If you say 2 inches deep, I assume you really mean cubic yards, as in how much you would have to buy? If so, the answer is 7.77, so you would need about 8 yards.
To solve this convert all measurement to a yard or square yard basis: 3 inches is 0.083333333333 yard and 1500 square feet = 1500/9 = 166.6666666666667 square yards Thus the amount of mulch you need is 166.6666666666667*0.083333333333= 13.88888888883333 cubic yards. so you need to purchase 14 cubic yards of mulch for the job.
I need to calculate the area of a baseball diamond (90x4) and convert it to square yards
You need to know how many meters are in a yard. One yard is .9144 meters, so 1 square yard = .9144 x .9144 meters (.836127) If 1 square yard is .836127 square meters, then 100 square yards is 83.6127 square meters.
To do this you need to know:60 second in a minute60 minutes in an hour1760 yards in one mileNow first work out how far one would travel running at that speed in one minute, by finding how far you would have traveled in one second-100/9.7 = 10.30927835051546 yards /secondThen multiply by 60 to get distance traveled in one minute =10.30927835051546 * 60 = 618.5567010309278 yards / minute.Now multiply by 60 again to get the distance traveled in an hour618.5567010309278*60=37113.40206185567 yards / hourOK we now know that we would be running at a speed of 37113.40206185567 yards an hour. BUT we want the answer in miles an hour, so we have to divide this by the number of yards in a mile:37113.40206185567/1760=21.09 miles per hour.Compare this with the related answer for this question where the distance run was in Meters (which are longer than yards - so you would be running faster)
~29,167 square yards
You will need 3.5 square yards of material to cover 32 square feet.
28 square feet = 3.1 square yards of material.
how many yards of netting this is 61" wide do i need for a space that is 11 feet and 8 inches long?
Lots
To fill in this size pool you'll need 100.5 cubic yards of material. If you mean how many gallons of water to fill the pool, you'd need 20,300 gallons of water to fully fill it.
You will need 18 pieces of border. 6 yards x 3 feet per yard = 18 feet
They need to eat 2 square yards.
You will need a minimum of 7.41 cubic yards.
4 yards is 12 feet, so you would have 4 inches left over
3 yards
he needs 30 yards
