Question

The length of a pencil box is 15 cm.what does this mean?

Answer 1

Length and breadth are the two basic dimensions of an object. We require two parameters during the two dimensional analysis of objects.

So here length of the pencil box can be considered as the measure of the longest side .It can be measured in m or cm etc. Usually length is considered as the longer dimension.

For 3d objects another measurement called height is also used.
