The volume of quartz depends on its shape and dimensions. To calculate the volume, you would need to measure the length, width, and height of the quartz specimen and then multiply these measurements together. The formula for the volume of a rectangular prism (which quartz often resembles) is volume = length x width x height.
The mineral would be classified as a member of the quartz group of tectosilicates such as quartz.Quartz. SiO2.quartz
This would depend upon a number of factors. Massive, or crystalline? Colorless, or colorful? Clear or opaque? Fractured or flawless? From the Swiss Alps, or from Arkansas? A buck a pound will get you good tumbling grade agate, but a well crystallized rose quartz specimen, or top grade rutilated quartz, or a nice Swiss smoky quartz crystal crowned with pink fluorite crystals... you can add two to four zeroes.
This would be quartz.
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.

Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Quartz - the term quartzite is applied to to low grade metamorphic rocks formed predomiently of quartz, mostly they are altered sandstones. Alog with the quartz there may be low abundances of many different minerals e.g. mica, or feldspar.
Quartz because its harder than calcite and the quartz in thicker.
