How much area would a billion grains of sand fill?
If fine sand has roughly 100,000 grains per cubic inch, then I make that 5.8 cubic feet (or about 43 liquid gallons). In terms of AREA, that would depend on how thick you spread out that sand. In very rough terms, I would say it would take up about 9 normal buckets. (average bucket size is about 5 gallons) (1 cubic foot = (12x12x12) cubic inches = 1728 cubic inches) Therefore, 1 cubic foot contains 1728 x 100000 fine grains = 172800000 1000000000 / 172800000 = 0.1728 1 / 0.1728 = 5.787
Is there more grains of sand or drops of water on the earth?
More drops of water due to the fact that the ocean is hundreds of miles deep. Sand is only on the surface. Water also makes up 3/4 of the world ... At its deepest point, the ocean is only 7 miles deep. The average depth is about 2-1/2 miles. But still: According to the USGS, there are just shy of 1.4 billion cubic kilometers of water on Earth from all sources. Each cubic km contains 10^15 milliliters. A "drop" is a rather imprecise measure, but let's use 16 drops per ml. So, all told, we're looking at approximately 2 * 10^25 drops of water. By some estimates, there are about 10^22 grains of sand on Earth. So there are a lot more drops of water than grains of sand.
How many cubic yards in a tandem load?
The average tandem axle truck can carry about 12 cubic yards of soil. Generally, a tandem axle truck has three axles.
What is the average density of soil?
For purposes of civil engineering, an average soil will have a density of about 100 to 110 pounds per cubic foot. (This can vary a little depending upon how well compacted the soil is.)

What is pollen rate?
There is no such sense of a pollen "rate," but there is of a pollen count. Which means the average pollen grains in a cubic meter!
What is the range of pollen count?
Pollen count is the measurement of the number of grains of pollen in a cubic meter of air. The higher the number, the more people will suffer if they are allergic to a particular pollen. Usually, the counts are announced for specific plants such as grass, ash or olive. These are tailored to what is usually a common plant in the area being measured.
How do you convert grains to cubic centimeters?

How many sand grains is in a cubic ft?
It depends on grain size, which can be as small as 0.004 inch or as big as 0.1 inch. If we take an average grain size of 0.02 inch diameter that is 0.00000043 cubic inch volume and a cubic foot is 1728 cubic inches then (not considering packing voids) that is 1728/.000000 = 4 billion grains!
What are rounded grains?
Rounded grains are those that used to be a cubic block and due to chemical weathering the edged have weathered. This led to a rounded grains.

What is the density of sand per cubic centimeter?
Since about 20 grains of sand lined up is 1cm, then I can use the volume formula (bwh) and subsitute in 20 grains of sand. 20*20*20=8000. There are about 8000 grains of sand in a cubic centimeter.
What is an average number of leukocytes found per cubic millimeter of blood?
There are approx. 7,000 leukocytes per cubic millimeter of blood.
What is the formula for converting square yards to cubic yards?
multiply the number of square yards - which is an area - by the average height in yards to get the volume in cubic yards
