Well, honey, a teepee is technically a shell structure. It's made up of a flexible covering draped over a frame, which is pretty much the definition of a shell structure. So, yeah, you could say a teepee falls into the shell structure category.

A pencil case is not typically considered a mass structure. Mass structures are typically large-scale structures like buildings or bridges that are made with heavy materials to support their weight and resist forces. Pencil cases are small and lightweight, primarily designed to hold and organize stationery items.
An eraser is considered a solid structure. It is typically made of a solid, homogeneous material such as rubber or vinyl, with a uniform composition throughout its volume. The eraser's physical properties, such as its flexibility and ability to deform under pressure, are characteristics of a solid structure. In contrast, a frame structure would be composed of interconnected parts or elements that work together to support loads and distribute forces, which is not the case with an eraser.
A pencil case is typically considered to be a container or a holder used to store pencils, pens, and other stationery items. It can be made of various materials like cloth, plastic, or metal, with compartments for organizing different items.

A pencil case is called 'une trousse'; "In my pencil case I have a pencil" is "dans ma trousse il y a un crayon."
Simply unzip the pencil case, reach in, and carefully grab the pencil to pull it out. Be sure to watch out for any sharp edges or other items in the case while removing the pencil.
The volume of a pencil case is about 1 millimeter cubed.
