You cannot, there is no single-rule, formulaic relationship between mass and physical measurements like length or diameter.
Density or weight is calculated by mass/volume
to find the of a solid length x width x height, and mass divided by density if the first 3 measurements weren't given
You measure its length, breath, height and mass. Then Density = Mass/(Length*Breadth*Mass) in the appropriate units.
Multiply them: density*volume = mass
momentum = mass x velocity => mass = momentum / velocity
You cannot. Diameter and length can, for some particular shapes, give you the volume. But that will not give you the mass unless you know the density of the substance.
Density or weight is calculated by mass/volume
Mass is more closely related to magnitude because mass is a measure of the amount of matter in an object, regardless of its size or shape. Diameter, on the other hand, is a measurement of the distance across an object, which may not necessarily correlate with the amount of matter present.
To determine the area, you would need to know the density, mass, and length of the object. First, divide the mass by the density to find the volume. Then, divide the volume by the length to find the cross-sectional area.
As you have not given the shape of the bar but ask for a diameter I am going to assume the bar is cylindrical in shape. From the mass and density the volume can be calculated: density = mass / volume → volume = mass / density From the volume the diameter can be calculated: volume_cylinder = π × radius² × length → radius = √(volume / (π × length)) And diameter = 2 × radius However, as density is mass/volume, and mass and volume both have units, density has units which you have neglected to include; is it kg/m³, kg/l, kg/cm³, kg/mm³, g/m³, g/l, g/cm³, g/cm³, lb/ft³, lb/in³, t/ft³, etc? (The common metric ones are kg/m³ and g/cm³.) A quick search shows that it should be 7.86 g/cm³,;the calculation needs to be done with consistent units, so I'll take the easy option and work with the mass in g and the lengths in cm: 1 kg = 1000 g 10 mm = 1 cm So we have: mass = 47.3 kg = 47.3 × 1000 g = 47300 g length = 625 mm = 625 ÷ 10 cm = 62.5 cm density = 7.86 g/cm³ And can now calculate: diameter = 2 × radius → diameter = 2 × √(volume / (π × length)) → diameter = 2 × √(mass / (density × π × length)) → diameter = 2 × √(47300 g / (7.86 g/cm³ × π × 62.5 cm)) → diameter = 2 × √(47300 / (7.86 × π × 62.5) cm²) → diameter ≈ 11.1 cm = 11.1 × 10 mm = 111 mm
to find the of a solid length x width x height, and mass divided by density if the first 3 measurements weren't given
You measure its length, breath, height and mass. Then Density = Mass/(Length*Breadth*Mass) in the appropriate units.
Volume= Length x Height x thickness = Mass ---------- Density So, Thickness = Mass ---------------------------------- Density x Length x Height
"16 mm" probably refers to the diameter. The mass of a steel bar depends not only on its diameter, but also on its length.
You don't need density to find mass. In a lot of question you need to find density with the given mass and volume. But to find density you would use a triple beam balance. To find volume you would either measure the length, width and height or you could fill a beaker up with water lets say 50g and then put the object in the beaker and lets say it raised up to 80g all you have to do is subtract 80g-50g=30g. To find density with volume and mass you divide mass------volume and get density.
To calculate weight or mass when diameter and height are given, you first need to calculate the volume of the object using the formula for the volume of the shape (e.g., cylinder, sphere). Once you have found the volume, you can then calculate the weight or mass by multiplying the volume by the density of the material. Weight can be calculated using the formula Weight = mass x gravity.
Mercury has a diameter of about 4,880 kilometers and a mass of about 3.3 x 10^23 kilograms. It is the smallest planet in our solar system by diameter and the second smallest by mass.
