Well, first of all, every school desk ... and every other solid object ... has three sizes: its length, its width, and its height. In the case of a school desk, none of these is likely to be about 30 millimeters. That's only a little more than 1 inch ... about as long as the end of your thumb. I don't think 30 centimeters is reasonable either. That's only about 1 foot ... about the length of a size-12 shoe. 30 meters doesn't work either. That's roughly 98 feet ... more than your house probably is, long, wide, or high.
