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.

desert soil is dry and prairie gets an average amount of rain
Topsoil has the greatest amount of organic matter
Use a measured water cylinder, drop in the object, the amount of water displaced represents the volume of the object
bedrock
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.
The amount of energy in food is measured in kilojoules (kL)
Either. It depends on the amount of liquid to be measured and the precision required.
Volume is measured in cubic units.
Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula. KVA = Volts * Amps / 1000
Only if... (a) you know the weight of a measured amount of tarmac - and (b) you know what depth the tarmac is. If you can calculate the volume of tarmac, and you know the weight of a specific amount - you can convert to tonnes.
