Answer 1
It is necessary to assume that the shape is a sphere, since that is the only shape whose volume is determined by only its radius/diameter.
Radius = Diameter/2
Volume = 4/3*pi*r3 or 1/6*pi*d3
Weight = Density*Volume
Answer 2
If you are given length as well as diameter, the object could be in the shape of a cylinder. The formula for the volume of a cylinder is V = (pi)r2h. Use the formulas for radius and weight given in answer 1.

How do you calculate weight of a precast jersey barrier?
Calculate the cross-sectional area of the barrier in square feet, multiply the area by the density of concrete (150 pounds per cubic foot), and multiply the answer by the length of the barrier in feet.
What is the formula for calculating weight of round ms bar?
Density = mass/volumeThe unit weight of steel is 7850 kg/m3volume of bar = (πd2/4)*Lhence mass = ((πd2/4)*L)*7850= ((3.14 *d2/4)*1)*7850 for unit length= 0.785*d2*7850= 6162.25 d2 if d is in metersor d2 /162 if d is in mm.By putting the value of diameter of rod, you can calculate the unit weight of any size tmt bar.
Relationship between volume of cube and diagonal length?
3 meter shaft is connected to a motor to a generator calls for the use of the use of the shallow shaft with an inner diameter of 100mm and the outer diameter of 150mm.knowing that the allowable shearing stress is 85 Mpa . determine the maximum torque that can be transmitted a) by the shaft as designedb) by a solid shaft of the same weight the material density is7800kg/m^3 .
How do you calculate weight if length width and thikness given of hollow shaft?
You cannot. The mass depends on the material of the shaft and that has not been specified.
What is the weight of a ball having density 2.86 cm and 12.6 cm volume?
It is not possible to answer the question because: density is not measured in cmvolume is not measured in cmwhile mass = density*volume, weight in not directly related to density.It is impossible to guess the correct units for density and volume.

How do you calculate unit weight of steel?
weight of all steel can be calculated by multiplying unit volume with density.
Weight calculation from height and diameter?
Height and diameter will give you the volume, if you know the density you can then calculate weight from that.
How do you calculate sheetmetal duct weight?
hello dude...... First find the area as u done length*breadth*height. Then multiply it with density of that sheetmetal. if it is steel (density is 7850 kg/m3). make sure your units of m (those in area). Now u got the weight of that sheet metal Cheers lax pushpak_tech@yahoo.in
What is the formula of calculating weight of a round bar of en1a material if its diameter and length is given?
Density or weight is calculated by mass/volume
Calculate the weight of ms pipe having diameter of 250 mm and one meter length?
D=Diameter L=Length ={(D^2)/(162)*L}
How do you calculate weight from length?
You cannot. Ask yourself how much does a mile weigh, or a foot, kilometre etc.You need more information such as what material, the other dimensions and the density.
How do you calculate density of a rectangular solid?
Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
Weight of 12mm diameter and 1meter length steel?
13mm diameter & 3100 length pl. give me weight
How can you calculate the weight of solid shaft 20 mm diameter and 1 feet length?
Without knowledge of the material you cannot.
What is density of drywall?
Weigh the material in pounds. Then measure the length, width and height. Do this in feet. Calculate the volume by multiplying length x width x height = Volume. Volume = length x width x height Divide the weight by the volume: Weight / Volume Density = Weight / Volume Your density is in units of lbs per cubic foot
How do you measure the weight of an object with the length and width and height given?
You can either use some weighing scales to measure it, or calculate the weight by using the density of the substance that makes up the object:weight = density x volume= density x length x width x height.
What is the weight of a MS rod whose dimensions are 40mm diameter?
You need the length of the rod to compute the weight. To do so, you can calculate the volume of the rod, which would be length*Pi*22 multiplied by the density of MS, which is 7.86 g/cm3, or simply 15.72(Pi)*length of the rod Mildsteel rod 40mm dia. = 9.85 kg per metre. I think that is what you asked.
