The word volume in math refers to the amount of space inside any kind of shape.

 

Did you know that the price tag of a vehicle is based on this volume concept? Consumers actually pay for the volume of the combustion chamber inside the engine; the more volume an engine has the more expensive the vehicle is.

Trades workers encounter solid or three-dimensional figures in the form of tanks, pipes, ducts, boxes, birthday cakes, and buildings. They must be able to identify these geometric solids and their component parts and compute their volume.

Have you ever had the experience of measuring the amount of space in a tank, a refrigerator or other three-dimensional figures? Volume is the term for measures of the size of three-dimensional figures. It is the amount of space inside an object or the amount of space an object occupies.

A cube is convenient to use as a unit to measure an object’s volume. The number of units needed to fill a figure is its volume.

EXAMPLE

If 1 cubic unit represents 1cm3, what is the volume of the following figure?

episode 23

SOLUTION

By counting the units, we can figure out the volume of an object. The volume of the figure is 12 cm3 because there are 12 cubic units in it.

Volume is related to length, so units of measure for volume are also related to units of measure for length. Volume like length can be measured in both metric units and inch-based units. Check out the table here to see both systems side by side, symbols, under what other names volume might show up in trades tasks and how volume is different from capacity: See more on capacity vs volume in  Episode 26 ADVANCED.

A Short Review

Volume or space relates to the size of a 3-D object. Only objects have volume or take up space. Solid objects have one volume, hollow objects have two: a bigger outside and a smaller inside Volume/space, depending on wall thickness of the object. In everyday context the idea of volume or space might be expressed using different words, such as box size, tank size, capacity, trunk size, garment size, serving size, engine size.

Volume or space is usually measured in cube units such as cubic feet, cubic meters, cubic inches.

A cubic foot is a cube with a length of 1 foot, a width of 1 foot and a height of 1 foot.  A cubic cm is a cube with a length of 1 cm, a width of 1 cm and a height of 1 cm.

Some other units of measure don`t seem related to volume first, but they are: bushel, gallon, teaspoon, board foot are all units of volume.

Volume or space is a 3-D or 3 dimensional concept. It always implies Length, Width and Height that a 3-D object or space has. Only objects have volume or take up space. Solid objects have 1 Volume, hollow objects have 2: a bigger outside and a smaller inside Volume/space, depending on wall thickness of the object. Filling a hollow space can be partial or full.

Volume can be measured in Metric or Imperial units, many of these are used only in specific industries. For example grain harvest size in bushels is mostly applicable to grain storage and transport. Volume of wood in trees or logs measured in cords or board feet only relates to logging and lumber production. Space inside a combustion chamber of an engine in cubic inches is only used in automotive parts context. Suitcase, bag and garment sizes and suitability for air travel is concern for manufacturing industry.

Some volume units of measure are funny or anecdotal, they work unofficially as figures of speech. “A 10-gallon hat” relates to volume, so does “a sinkhole the size of 5 Olympic swimming pools”. It could be meaningfully used to indicate Volume during rescue or evacuation.
