Depth

In math, the distance between the nearest end and the farthest end of an object is its depth.

For example, the depth of a box can be measured. When the distance between one end of the box and another end of the box is found, the box's depth was measured.

 Depth in Liquids 

For liquids, the distance between the top or surface of the liquid and the bottom of the liquid is the liquid's depth.

For example, water is a liquid. If a container is filled with water, the distance between the top of the water and the bottom of the container is the water's depth.  If the depth is big, the water is deep.
