Squares cannot be used to measure a three-dimensional volume since they have only two dimensions. Squares are used to measure surface areas, such as the outer surface of a rectangular solid.
Cubes are used to measure volume because they are the simplest geometric division of a three-dimensional space. For a rectangular solid, multiplying H x W x D literally tells you the number of cubes (of the given unit of measurement) that can be contained within that space.
It is easiest to measure the length, breadth and height and multiply them together.
length X width x height
-- Measure the length, width, and height of the prism. -- Multiply the three numbers. The result is the volume of the prism.
You have omitted the dimension of 'length' Volume -= length X Width X Height.
A rectangular prism whose edges measure 3 ft 3 ft and 2ft has a volume of 18 cubic feet.
For the same reason they chose to measure volume in cubic units
A ruler or tape measure.
There is not an instrument designed to measure the volume of a rectangular box. You would use a ruler or tape measure or similar to measure its linear dimensions and a brain to multiply them together.
It is called its volume.

It is easiest to measure the length, breadth and height and multiply them together.
length X width x height
Base x Height x Width = Volume of any rectangular prism.
If the volume of the smaller rectangular box is 27 in3, what is the volume of the larger rectangular box?
-- Measure the length, width, and height of the prism. -- Multiply the three numbers. The result is the volume of the prism.
Measure length times width times hei ghth
You need to measure the length, breadth and height and multiply them together.
