i dont know and why are u cheating?? wernt you paying attention in class!
A cross vault is actually two barrel vaults intersecting at 90 degrees. The big advantage that the Romans saw in this was it's structural integrity. Their buildings were much stronger and durable using these types of arches.
The Roman architectural invention that enabled the construction of larger enclosed buildings was the arch, particularly in combination with the vault and dome. The use of the arch distributed weight more efficiently, allowing for taller and wider structures. This innovation led to the development of monumental buildings such as the Pantheon, which features a massive dome that remains the largest unreinforced concrete dome in the world. Such advancements in engineering allowed Romans to create expansive and durable public spaces.
It is unknown when the vault of King Djoser was robbed. The only remains left in the vault was a mummified foot.
VAULT
The Romans effected what historians call the Roman architectural revolution or concrete revolution. This involved the extensive use of concrete, the barrel (simple) arch and the vaulted arch. These three elements enabled the Romans to go beyond Greek methods of construction which used cut-stone and post-and-beam or post-and-lintel structures. They became essential for large roofs and large buildings, such as basilicas (public buildings) amphitheatres (arenas), theatres, baths, domes, forts and fortifications and dams. They also made it possible to build bridges which were much longer than before and could cross much wider rivers and valleys. Prior to the Romans concrete was hardly used. The Romans were the first to made large scale use of it. They developed a type of concrete (opus caementicium) which was as resistant as modern concrete. It also set underwater and therefore could be used to build docks for ports, dams and bridges. It was less fluid than modern concrete and had to be layered by hand. It was made by mixing a volcanic rock called pozzolana (which is named after Pozzuoli, a suburb of Naples) with lime. The two acted as a binder and rubble from stones, bricks or pottery shreds were added as aggregates which added body to it. Concrete had technical and practical advantages. It was exceptionally strong. it could be moulded and could span great distances when shaped into arches, vaults and domes. It was layered into a formwork and it took the shape of its container. It did not require skilled labour and therefore was cheaper.. It was much faster for construction than laborious masonry walls. It was safer because concrete vaulted roofing was fireproof, unlike the wooden-beamed roofs of traditional post-and-lintel construction methods. The potential of the previously very little used arch and vault, were fully exploited for the first time. The Romans were the first to fully appreciate the advantage of these structures and make large scale use of them. The Etruscans are thought to have invented the simple (barrel) arch. The oldest example of the vaulted arch has been found in the Greek city of Pergamon (in western Turkey). The (simple, barrel) arch has a strong load- bearing capacity and was useful to build large walls without using the post-and-lintel method and to build bridges which were much longer than ever before. The vault (vaulted arch) has an even greater load-bearing capacity and its structure is suited to support large roofs. Their construction in concrete made them easier to build and even stronger. This led to the use larger and monumental arches and vaults on a grand scale. However, the Romans did not abandon masonry arches and vaults. The vaulted arch came into two forms: the groin arch is formed by two to four intersecting barrel (simple) arches and the rib arch, where the intersecting arches were of different diameter. Concrete was also used to assist the construction of the stone-paved roads, which were a Roman invention. A ditch was ploughed down to the firmest layer of ground that was found. The ditch was filled with rubble from local materials or sand (when it could be found) up to one metre from the surface level. A flat floor of compacted gravel was made. Then a surface was made by embedding the stones in concrete to create the paving. The concrete was laid in two thin layers. The bottom one had coarse concrete and the top one had fine concrete.

What advantages did the Romans find in using a cross vault instead of a barrel vault?
The arch and the vault The Romans did not invent but did master both the arch and vault, bringing a new dimension to their buildings that the Greeks did not have. Domes Concrete As well as mastering and refining Ancient Greek geometrical learning, the Romans had their own wonder material. Concrete freed the Romans from building only with carved stone or wood.

They were concrete, the barrel arch and the vault.
Washington DC has many buildings that have been influenced by the Romans. The arch, vault, and dome are all from the Romans.

Cross vault
The construction of the Colosseum in just eight years was made possible by the use of the three key elements of what had been called the Roman architectural revolution which enabled the Romans to go beyond the Greek post-and-lintel system of constructing buildings: concrete, the arch and the vault. The core of the structure was made with Roman concrete (which was different than modern concrete), which was covered with stone and stucco (a type of plaster) because concrete was unsightly. Local tuff stone and travertine stone, which was brought from 20 miles from Rome, were used. The outer facade was covered with travertine stones which were braced by 300 bronze clamps. Before building the Colosseum an artificial lake which had been created by the emperor Nero had to be drained and filled. Local water streams were canalised. Its foundations, also made in concrete to provide a very solid base, are 12-13m (39-42 ft.) deep and were designed in strips beneath concentric walls. Its tiers are supported by vaults. Three of its four tiers have 80 arches. The arches provided 80 entrances; 79 were for the general public and the rest were special entrances. The actual arena was 86x54 metres (282x177 feet) and was separated from the seating by a 4 metre high platform. Underneath the partly brick and partly wooden floor of the arena where the gladiatorial fights and the animal hunts were performed there was a hypogeum (which means underground). This was a complex underground structure with 12 curved tunnels on the sides of a central passageway. The gladiators and caged animals were housed there prior to the show. It also stored machinery and props for sceneries. There were pulleys to hoist the caged animals.
The arch and the vault The Romans did not invent but did master both the arch and vault, bringing a new dimension to their buildings that the Greeks did not have. Domes Concrete As well as mastering and refining Ancient Greek geometrical learning, the Romans had their own wonder material. Concrete freed the Romans from building only with carved stone or wood.
The Romans rarely combined arches and columns. Large Roman buildings, the bridges and the bridgework of aqueducts made extensive use of the simple (barrel) arch and the vaulted arch (or vault, for vaulted roofs). Arches did not need columns. When the Romans combined arches with columns it was for decorative purposes. Roman ttemples were based on Greek models and were post-and-lintel structures resting on columns. Because of this, they did not have arches.
