What is a Cubic Inch? The Unit of Volume Explained

What is a cubic inch? The unit of volume, also known as a cubic inch, measures the amount of space something takes up in three dimensions. 

It can be used to measure objects or spaces around you at home, work and elsewhere.

The term "cubic" is used because there are three dimensions that make up an object's volume: height (H), width (W) and length (L). 

The total volume of an object or space is equal to its H x W x L measurements multiplied by each other. For example, if you have a rectangular box whose width and length are both 2 inches longer than its height (H=2", W=4", L=6"), then its total volume would be 8 x 4 x 6 = 192 cubic inches.

The volume of a regular, irregularly shaped object is calculated by measuring the length, width and height with a ruler and multiplying those dimensions together.

For example, if you have a rectangular box whose width and length are both 2 inches longer than its height (H=2", W=4", L=6"), then its total volume would be 8 x 4 x 6 = 192 cubic inches.

What is the Unit of Volume?

A volume is a measure of how much space something occupies. It's usually used to describe how many units of a given thing can fit into one unit of another thing. 

For example, you might say that your car has a volume of three cubic feet, or that your living room is 25 cubic feet (but you'd probably just say it's big).

Some common units of volume include:

  • Liter - 1 liter = 1 cubic decimeter (100 cm3) = 1,000 milliliters
  • Cubic foot - 1 ft3 = 12 in. x 12 in. x 12 in., or 0.028316 m3

Cubic meter - 1 m3 = 1000 liters

Popular Unit of Volumes?

There are many different units of volume. The liter, gallon and quart are the most commonly used units in the United States. They're also easy to understand because they're based on everyday objects that we can relate to: a liter is about the size of a soda bottle and a gallon is about as big as your average kitchen sink.

The teaspoon and tablespoon are used for measuring smaller amounts of liquid than cups or quarts/liters would be appropriate for—for example, if you have just half an egg left over after making something like scrambled eggs or omelettes (and don't want to use up another whole egg). 

A tablespoon measures out at around 2 tablespoons worth while a teaspoon measures out at around 4 teaspoons worth—so if you want to measure 1 cup (8 oz) worth of water using teaspoons instead of cups then it'll take 16 teaspoons!

The teaspoon and tablespoon are also used for measuring small amounts of solid ingredients, such as when making a cake or cookies. The difference between the two is that teaspoons measure out smaller than tablespoons, so if you want to measure 1 cup (8 oz) worth of flour using teaspoons instead of cups then it'll take around 32 teaspoons!
