Select an item to label. Determine the category or label that best describes the item. Attach the label to the item using a label maker or adhesive label.
To determine the weight of yarn without a label, you can use a scale to measure the yarn's weight in ounces or grams.
To label the volume of an object, you typically use cubic units (e.g., cubic centimeters, cubic inches) or simply "units cubed" (e.g., cm^3, in^3). This signifies that the measurement represents the space occupied by the object in three dimensions.

To label a prepositional phrase, you identify the preposition and its object. The preposition typically comes before the object, which is the noun or pronoun that the preposition refers to. This combination of the preposition and its object forms the prepositional phrase.
If you assume length to be a subjective term generally referring to the dimension with the longest measurement, then for this object W (width) is equivalent to length, in which case you may like to think of D (depth) was width instead.It depends on your perspective in relation to this object. Lets say this object is a (extendable) desk and the units are inches - if you are facing the desk, you will see it is 29.5" high (perhaps roughly hip height). Since the dimension which measures 39" extends away from you, the most appropriate label is depth.W X D X H is the usual way to describe the dimensions of an item of furniture or similar. W X L (X H) is normally used for more tranportable objects for which your perspective would be changing. For example, a mail package.
The proper unit to label an object's speed is meters per second (m/s) in the International System of Units (SI).
