'Dry' volume - is measures in cubic centimetres... 'Wet' volume is measured in millitres.
SI units are more accurate than English system units
A graduated cylinder is a piece of laboratory equipment used to measure the volume of a liquid and are generally more accurate and precise than laboratory flasks and beakers.
English (or imperial) units are things like:- Pint/gallon for volume Inch/foot for length Ounce/pound for weight (there are more) Metric units are:- litre for volume metre for length kilogram for weight
Millilitres are units of volume, grams are units of mass. They cannot be directly converted without more information.
The base unit for liquid volume in the metric system is the liter (L). One liter is equivalent to 1,000 milliliters (mL) and is commonly used to measure liquids in various contexts, such as beverages and laboratory solutions. In the International System of Units (SI), the cubic meter (m³) is also a base unit for volume, but liters are more commonly used for everyday liquid measurements.
grams or kilograms (more often)
it can be but its more often measured in liters
Derived units are made by combining base units using mathematical operations such as multiplication and division. They are used to express physical quantities and their combination is necessary to represent more complex measurements, such as velocity or volume. Examples of derived units include meters per second for velocity or cubic meters for volume.
It depends on the system in which you are working, but the units will be the same as for a regular solid. In the International System of Units (SI units, for short), the unit for volume is m3.
Either could be but the conversion from length to area and volume, in terms of units, is simpler. Area = Length2 and Volume = Length3. If Area were the base, then Length = Area0.5 or sqrt(Area) and Volume = Area3/2 - not a convenient relationship. If Volume were the base, then Length = Volume1/3 or cubert(Volume) and Area = Volume2/3 - again not a convenient relationship. Length is required far more often than area or volume in other dirived measures such as speed, acceleration, force, power and so on. So having to calculate roots is making life complicated uncessarily!
If the rectangular pyramid has a base of L x B square units, and height H units, then its volume is 1/3*L*B*H cubic units. You would need to convert one or more of L, B, H into units which incorporate pi, which would be a very pointless exercise.
