In scientific classification of biota, a subphylum is a taxonomic rank in zoological nomenclature. The taxonomic rank of 'subdivision' in fungi and plant taxonomy is equivalent to 'subphylum' in zoological taxonomy.
Another general rule is that your driveway should be around 10 to 12 feet wide, and a few feet wider at the curves. If you have space, itâs always a good idea to provide a larger area at the top for turning around or for additional parking when needed. A 12âx18â space or larger is ideal for this.
For example, a standard concrete driveway is usually 4 inches -- 0.33 feet -- thick. If the driveway is 100 feet long and 6 feet wide, you need 200 cubic feet of material. That's 7.4 cubic yards.
