A hollow prism is a prism that is empty inside, without any material filling. It lacks the usual glass or crystal structure of a standard prism. It primarily functions to refract or reflect light due to its geometric shape.
Glass can absorb heat and sound. Glass can be formed or molded into any shape. Silica is a common constituent of glass. In nature, when lightening strikes sand, it forms hollow, branching root like structures called fulgurite.
Marine vessels float in water due to the principle of buoyancy, which is the ability of an object to float in a fluid. The weight of the water displaced by the vessel is equal to the weight of the vessel itself, resulting in a balance that allows the vessel to float. The shape of the vessel also plays a role in determining its buoyancy.
Depends on the shape of the vessel. Different shape, different formula.

Glass perfume bottles are typically made through a process called glass blowing. In this process, glass is melted in a furnace and then shaped by blowing air into a mold or using a hollow iron rod to give the desired shape. Once the glass cools, it is cut and polished to create the final design of the perfume bottle.

The shape of water in a drinking glass typically conforms to the shape of the glass itself, taking on a cylindrical or conical shape. It fills the container from the bottom up, forming a level surface at the top due to gravity.
A tube is a hollow cylinder.
