Yes, dimensions do have a size. A dimension is an abstract concept that describes the particular characteristics of an object or group of objects. It’s a way to measure the physical properties of the object, like height, width, depth, and time. A size is the measure of how big something is, usually expressed in linear measurements such as feet, meters, or inches.
Let's look at some examples.
Height - Height is a measurement of how tall an object is from the ground to its highest point. We usually measure height in feet or meters.
Width - Width is a measure of how wide something is from side to side. We usually measure width in feet or meters.
Depth - Depth is a measurement of how deep something is from the surface to its bottom. We usually measure depth in feet or meters.
Time - Time is a dimension that is used to measure the passing of days, months, and years. We usually measure time in seconds, minutes, hours, days, weeks, and years.
These are all examples of dimensions and their sizes. Dimensions are important when it comes to understanding the physical properties of things and measuring their size.
