Is it true that volumes of solids can be expressed in liters or milliliters?
Liters and any denomination of liters are a unit of volume. The definition of matter includes that it has to take up space - volume. So you can indeed use liters and milliliters to measure the volume of a solid. However, the alternative is to use meters (cubed) and any denomination of meters to represent volume. You could say that something is 1.00 liters or you could say that the same thing is 1000 cm3.
Impossible to answer because cubic centimeters are a VOLUME, and millimeters is a LENGTH. Perhaps you meant to use the word 'millilitres' which IS a volume. Milliliters and Cubic Centimetres are ALWAYS equal to each other. The volume of LIQUIDS are usually expressed in milliliters ( ml) and the volume of SOLIDS are usually expressed in cubic centimeters (cc)
Cavalieri's Principle states that two solids with equal heights and cross-sectional areas at every level have equal volumes?

Volume can be expressed in milliliters, liters, cubic centimeters (ml also), cubic meters, cubic kilometers, whether the volume is full of liquid, solid, gas, or empty. cm3, cubic centimetres (ml or cc more commonly) are used most often, certainly in chemistry but it is dependent on how large the volume is of course. In solids, it is more common to use weight, which is converted from volume, using density.
What is the ratio of the corresponding edge lengths of two similar solids is 49 what is the ratio of their volumes?
In the metric system, volumes of all kinds (solids, liquid, gases, plasma, etc.) are measured in liters. ------------------------------------------------------------ The litre (symbol L or l, the first is preferred) is not a true SI-unit; it is only an "accepted" unit of volume. 1 cubic metre (the SI unit) has 1 000 litres.
