how to calculate material weight example 10Cm20cm100cm?

Question

we always calculate iron plate,iron rod,stainless steel plate,cable,aluminium plate

Answer 1

Unfortunately, you will either weigh samples or you need to find a standard sample chart to calculate the mass based on:
1) a plate/rod/cable molecular formula (steel is an alloy, made of many elements or compounds...like iron, carbon, and coke (not an element)...and what is coke made of?) Is it high-carbon steel, rolled steel, is it milled or worked?
2)volume
3)density

For Structural Engineering, Civil Engineering, etc. standard plate and beam weights are listed in very detailed charts...search for "plate weight". Also, if you know how to contact the manufacturer, they may be able to tell you the weight/per foot (or more precisely, the mass per length or mass per volume)

For instance, a copper cable may be solid-core, stranded, braided, insulated, have an insulating core (like coaxial cable), etc. The best way to calculate material weight is to actually weigh a section of the plate/rod/cable and multiply the weight of section by the number of times the piece 'fits' into your volume.

This is kind of a strange question, because: rods do not fill a 'box' volume other than as a function of their diameter and length, leaving 'air' spaces. There truly is no "use this number" and you will know what this "box" of rods or plates weighs" based solely on the atomic or molecular makeup of the plates/rods/cable. Weigh some samples, multiply. That's the best way.

Answer 2

Weight is commonly measured using one of two methods. A spring scale or hydraulic or pneumatic scale measures weight force (strictly apparent weight force) directly. If the intention is to measure mass rather than weight, then this force must be converted to mass. As explained above, this calculation depends on the strength of gravity. Household and other low precision scales that are calibrated in units of mass (such as kilograms) assume roughly that standard gravity will apply. However, although nearly constant, the apparent or actual strength of gravity does in fact vary very slightly in different places on the earth (see standard gravity, physical geodesy, gravity anomaly and gravity). This means that same object (the same mass) will exert a slightly different weight force in different places. High precision spring scales intended to measure mass must therefore be calibrated specifically according their location on earth. Mass may also be measured with a balance, which compares the item in question to others of known mass. This comparison remains valid whatever the local strength of gravity. If weight force, rather than mass, is required, then this can be calculated by multiplying mass by the acceleration due to gravity – either standard gravity (for everyday work) or the precise local gravity (for precision work). Gross weight is a term that generally is found in commerce or trade applications, and refers to the gross or total weight of a product and its packaging. Conversely, net weight refers to the intrinsic weight of the product itself, discounting the weight of packaging or other materials

Answer 3

you can't calculate a material weight just by knowing the basic measurement of the material...but you can calculate the volume of the material...the volume for your example is 20 000 cubic cm...

so, if you want to know the weight of the material, you have to weight it...or you have to know some other details/properties of your material..

Answer 4

You give dimensions so a volume can be calculated, not weight, per se.

I agree, your question does not make sense. What are you asking?

Answer 5

hmmm? dont understand the question.
