A cubic yard of stone that is 4" thick would cover 9 square yards or 81 square feet. If you need to cover 7000 sq. ft., you would need roughly 86.5 cubic yards. That's a lot of rock.
You calculate the total amount of whatever it is that you want to find the silicon abundance for. Then you calculate the amount f silicon in that. Then percentage abundance of silicon = 100*amount of silicon/total amount Typically the amount would be measured as the mass.
percent increase=(new amount-original amount) _____________________ original amount
The simple way to calculate percentage is to divide the given amount by the total amount and then multiply the answer by 100 to get the percentage of the given amount in respect of the total amount
trend percentage= (analysis period amount / base period amount) x 100
It is a determined value or an estimate.

To calculate the amount of top soil needed, measure the length and width of the area to be covered in feet. Multiply the length by the width to get the square footage. Then, determine how deep you want the topsoil to be and convert that to feet. Multiply the square footage by the depth to get the volume of topsoil needed in cubic feet.
desert soil is dry and prairie gets an average amount of rain
To calculate density, you need to measure the mass and volume of an object. Mass is a measure of the amount of matter in an object, typically measured in grams or kilograms, while volume is the amount of space the object occupies, usually measured in cubic centimeters or milliliters. Density is then calculated by dividing the mass by the volume.
Use a measured water cylinder, drop in the object, the amount of water displaced represents the volume of the object

The amount of power they consume is measured in watts. The amount of light they put out is measured in lumens.
Enthalpy is a particular amount of heat that is produced or released at a given pressure. There are specific equations that must be used to calculate enthalpy.
To calculate the amount of topsoil needed, you can use the formula: volume = area × depth. For 28 square meters at a depth of 2 inches (which is approximately 0.0508 meters), the volume would be 28 × 0.0508 = 1.4224 cubic meters. Therefore, you will need about 1.42 cubic meters of topsoil to cover 28 square meters at a depth of 2 inches.
The amount of energy in food is measured in kilojoules (kL)
Basically a cube measuring 3 feet by 3feet by 3 feet. 1 cubic yard.
A typical scoop of topsoil can vary in volume, but it is usually around 0.5 to 1 cubic yard, depending on the size of the scoop. This amount of topsoil can weigh around 1,000 to 2,000 pounds, depending on its moisture content and composition.
