How many 40 pound bags of topsoil do you need to cover 5 acres at 3 inches depth?
You need (54,450/number of cubic feet of topsoil in each 40 lb bag) .-- One on-line source we consulted says that the weight of topsoil rangesfrom 50 to 100 pounds per cubic foot.-- Another one says that topsoil is usually estimated to weigh 1 ton per cubic yard(27 cubic feet). That would put it at 74.1 pounds per cubic foot ... right in the middleof the range given by the first source.I can see where this is going, and you're not going to like it . . .-- At 75 pounds per cubic foot, that puts 0.533 cubic foot in one 40-pound bag.-- You would need 102,094 of those bags to do the job !-- Even if the topsoil you get is exceptionally light, sandy, and airy, and a40-pound bag holds a full cubic foot, you still need 54,450 of those.
What does one cubic yard of river rock weigh?
One cubic yard of river rock will weigh around 4,050 lbs. or 2.03 tons You can make this conversion as follows: The cubic foot weight of the material must first be known. If your dealing with stone such as to be laid up in a wall or used for masonry construction it is good to take a 12" x 12" x 12" cube box made of 18 gage sheet metal and put your stone in it filled to the boxes capacity and packed as tightly and firm as possible ( the more solid the more accurate) and put it on the scales. Do this three times with different stones each time and add the three weights together, then divide the sum by three to get the average weight per cubic foot. If there are many viods in between the stone in the cube box take this into consideration; it is not accually a cubic foot solid and allow for a viod factor of 5% to 8%, add this to the over all weight for an idea of what a cubic foot weighs. Once you know the cubic foot weight all you have to do to know the ton amount is to multiply the weight per CF by 27 ( 27 is the number of cubic feet in a yard) and then divide their product by 2000 ( the number of pounds in a ton ) and that will be the number of tons per cubic yard or in your case pounds per cubic yard. Example: Your River rock weight is say 150 lbs per cubic foot. Then one cubic yard weighs: 150 x 27 = 4050 lbs. So there are 4050/2000 tons in a CY of river rock or 2.03 tons. Remember that a Cubic Yard is Volume and a Ton is Weight. One ton of feathers makes more cubic feet than say for instance one ton of silver. So to make this conversion you must know two constants, the weight per CF or CY for that matter and how many cubic feet you have. In this case it is 27 cubic feet or a "yard". Awenow
How many 1 foot tiles would it take to put along each side of a room 9 foot by 9 foot?
108 because you multiply 9 by 12 inches from th foot and get 108
How do you get the cubic feet of dirt is needed to fill a hole that is 20 feet wide and 15 feet long and 4 inches deep?
This problem gets easy quickly if you put everything in the same units. When you see 4 inches, think of one third of a foot. Fifteen feet times a third of a foot gives five square feet. Multiply 5 by 20, 100 cubic feet. If you are going to get the dirt by digging it from compacted soil, get 100 cubic feet. If you are getting loose dirt, better get 120 cubic feet - it will settle !
Is it possible for you to put your foot behind your head?
yes,but most people can not put their foot all the way behind their head.Some people who are very flexible probably can put their foot behind their head.
