**What is a cubic unit?**

In geometry, cubic units can be defined as the units used to measure volume. The volume of a unit cube whose length, width and height are 1 unit each is 1 cubic unit.

Here, the rectangular prism is made up of smaller unit cubes. The length, width and height of the rectangular prism can be measured by counting the number of unit cubes. The volume is then determined in cubic units.

Some examples of cubic units in metric units are cubic meters, cubic centimeters, and in customary units are cubic inches, cubic feet.

While solving word problems on finding the volume, emphasize on the how the single unit of length, width or height turns into cubic units.
