A net for a geometric solid is the 2-D pattern for constructing the 3-D shape.
A cylinder.
A 2d shape is a flat object (ex: square, circle, etc.) and a 3d shape is a shape in space (ex: cube, sphere, etc.)
It is a volume (3D) shape - "solid" has nothing to do with it.

A 3D star is not a standard shape. You can easily add another point.
Yes it is. Anything that is 3D is usually a geometric solid. (Think)
A cylinder.
A 2d shape is a flat object (ex: square, circle, etc.) and a 3d shape is a shape in space (ex: cube, sphere, etc.)
That is a rectangular solid.

The 3D house shape is called a rectangular prism. It is a three-dimensional geometric solid that has six faces, all of which are rectangles. The rectangular prism is characterized by having three pairs of congruent and parallel faces, making it a type of parallelepiped.
