First, things are not made of cement- they are made of concrete- which consists of cement, sand, gravel and water. Mix them using 1 part cement, 1.5 parts sand, 3 parts gravel.
To calculate how much CONCRETE you need, multiply depth X width X length in inches, then divide by 1728. This will tell you the number of cubic FEET of concrete. To get the number of cubic YARDS, divide the cubic feet by 27.
If you are using packaged concrete mix (Sakrete is one) then an 80 lb bag makes 0.6 cubic feet of concrete. NOTE: If you are working with concrete for the first time- do not add too much water (weakens the concrete) and do not get wet concrete on bare skin- it will cause a chemical burn. Wash it off promptly if you do.
20' by 26' by 5" requires at least 10 cubic yards of cement.
Forty five 80 pound bags of cement are needed to make one cubic yard of concrete.

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.
The answer will depend on how deep the cement needs to be.
for 100sft or 100cft
The amount of cement will depend on the size of the tile, since a larger trowel is needed for larger tile.
The amount of cement needed to set a fence post depends on the size and depth of the hole, but typically a 50 lb bag of cement is enough for one post.
Calculate the area to be covered. (A) Calculate the area per board or pack (B) Divide (B) into (A)
How do you calculate cement mortar in 230mm thick brick
You need the amount of water, the temperature of the water, and the desired temperature.
Solubility and amount of the substance
To find the volume of cement needed, first convert the depth to meters (10 cm = 0.1 m). Then, calculate the volume by multiplying the length, width, and depth: 7m x 0.95m x 0.1m = 0.665 cubic meters of cement are needed to cover the walkway.
To calculate the amount of concrete needed for a project, you need to determine the volume of the area to be filled with concrete. This can be done by multiplying the length, width, and height of the area. Once you have the volume, you can then calculate the amount of concrete needed by dividing the volume by the coverage area of one cubic yard of concrete. This will give you the total number of cubic yards of concrete needed for the project.
Limestone is refined to make portland cement.
A "mass airflow" sensor, measures the amount of air entering an engine to properly calculate the amount of fuel that is needed.
On average, one bag of cement is needed per fence post.
