Formula for calculating the weight of iron For example, a piece of iron is m 12x80, how much should its weight be? How to calculate the calculation formula? M 12x80 mm. How many kilos do I need to get the result. What's the density. How do you know?

12x80 is a millimeter unit
Weight calculation formula:
Weight = L x W x H x 7.8/1000
Among them: length, width and height are all measured in centimeters
The result is: kg
This problem lacks a thickness data
What is the density? You can find it in books or on the Internet,
For example, you can type iron density in Google
Or input: Steel density
Come and search, and you'll find it
The density of iron and steel is usually about the same
Generally: about 7.8, there are slight differences in density among different steels, for example, the possible densities are 7.83, 7.85 and 7.86
