The formula for calculating weight of a solid shaft is dia x dia x length x 7.8 x 1000000. This formula is the most commonly used.

For mass, you would use a triple-beam balance. For volume, you would either use a graduated cylinder (for liquids), calculate the displacement with a graduated cylinder (for an odd-shaped solid), or calculate it using the equation for volume (for a regularly-shaped solid).
how to calculate the radius of a cylinder
Density= mass/volume
no it doesn't .
Without knowledge of the material you cannot.
Weight savings.
Depends on what you mean by "better". For the same dimensions, a solid shaft will be a bit stronger, but also a lot heavier. If you were to make a hollow shaft of the same weight, but a bigger diameter, it'd be a lot stronger than the solid shaft.
Its grams
Shaft power P = (2(pi) * (angular Speed in rpm) * (Torque at shaft)/ 60 Torque of a solid shaft is given by (pi/16)* (Shear stress of material of shaft) * (Dia of shâft3).
The formula used to calculate the volume of a recrangular solid is:L*W*H=V
The formula used to calculate the volume of a rectangular solid is: L*W*H=V
You multiply its density by its volume.
d*d/162
just multiply length by height by depth/width.
Most of the force in a shaft is carried by the outer layers of the shaft, and very. very little by the center. By using a hollow shaft you get almost the same turning strength for a lot less weight and material.
