What is the base unit of measure of the volume of a solid?

The base unit of measure for the volume of a solid is the cubic meter, while the liter is often used for measuring liquid volumes. However, the cubic meter is also used for very large volumes of liquid, as 1 cubic meter is equivalent to 1,000 liters.

The cubic meter is often written as the letter "m" with a superscript "3," or m³, but since superscript characters are not always available, it is also written as cu m, m3, m**3 or m^3.

An easy way of visualizing the cubic meter is to think of a cube whose length, breadth and height all measure 1 meter. As a point of comparison, 1 cubic meter of pure water weighs 1,000 kilograms.

Other names for the cubic meter are stère and kiloliter.
