👉 In the context of mathematics, a subsolid is a solid that is a subset or part of another solid. It can be thought of as a mathematical representation of a material's properties in terms of its volume and density. For example, consider two solids (let's call them "solid A" and "solid B") that are made up of the same material and have the same shape. If we take a portion of solid B and place it inside a larger container to make a smaller solid,
