You multiply its density by its volume.
Most of the strength of a circular section comes from the outer diameter fibers where area and inertia are the highest. So a tube is more efficient than a solid in terms of strength to weight ratio. However, if you ignore the weight benefit of a tube, the solid steel is stronger of the same diameter. If you need a certain weight, then you can make the tube stronger by increasing its diameter over a solid section of equal weight.
A rubber band is a solid.
Solid? or Hollow?
yes ruber is solid.
Without knowledge of the material you cannot.
solid
Crystalline
A(n) amorphous solid.
No, rubber is an amorphous solid. Glass, rubber, and many plastics are amorphous solids. Not all solids contain crystals.
Because the hollow ball is larger than the solid one. It displaces enough of the fluid to equal its weight, so it floats.
a bicycle tire is a solid, because it is made out of rubber and rubber is solid. so, therefore, a bicycle tire is a soid.
