Answer:
The attributes of a three-dimensional figure are faces, edges and vertices. The three dimensions compose the edges of a 3D geometric shape. A cube, rectangular prism, sphere, cone and cylinder are the basic 3-dimensional shapes we see around us. In geometry, matrices are widely used for specifying and representing geometric transformations (for example rotations) and coordinate changes. In numerical analysis, many computational problems are solved by reducing them to a matrix computation, and this involves often to compute with matrices of huge dimension.
The Great Chain of Being refers to hierarchy in a system,which definitely exists in Dante's Inferno. You can see as the protagonist goes through Hell that first he goes into Limbo, where the least serious criminals and people who haven't been Christened are located. As he goes through nine circles of Hell, he comes across more serious offenders and demons who guard them, until he comes into the very core of Inferno where Satan is keeping 3 people prisoners: Judas, Brutus, and Cassius.
Hope this helps! :)
