A cell's volume is the amount of material that can fit into the cell. A cell's surface area is the total amount of material that makes up the outside of the cell. The ratio of surface area to volume is the amount of surface area per unit volume of an object or collection of objects.
A small cell will have a larger surface-to-volume ratio.
Look in the book broseff.
As a cell becomes larger the surface area to volume ratio gets smaller. The volume increases by the square of the surface area. That is the main reason that one celled organisms are small.
The larger the surface area to volume ratio of a cell, the smaller its size (and vice versa).

Lets say the cell is cuboidal. The surface area of a 1 inch cube is (1X1) 6 or 6 square inches. The volume of the cell is HXWXH or 1X1X1 or 1 cubic inch. The ratio of surface area to volume is 6:1.
Columnar cells are cells in which their height is at least four times their width. A Cuboidal Cell is a cell a cube-like shape where its width is about equal to its height.
Glial is not a type of epithelial cell.
* Simple Cuboidal Epithelium. As their name implies, cuboidal cells are roughly square or cuboidal in shape. Each cell has a spherical nucleus in the centre. Cuboidal epithelium is found in glands and in the lining of the kidney tubules as well as in the ducts of the glands. They also constitute the germinal epitheliumwhich produces the egg cells in the female ovary and the sperm cells in the male testes.
Squamous , cuboidal , stratified , columnar , pseudostratified are types of epithelial cells .
Simple cuboidal epithelium is a one-cell layer of cuboidal cells (equal sides) that are found in many glands and ducts and forms “tubes” or ducts.
Epithelial tissue that is only one cell thick is known as simple cuboidal epithelium. The epithelial tissue that is found in glands are glandular.
Simple For example, simple cuboidal epithelium A layered version would be Stratified cuboidal epithelium
squamous (flat and scalelike)cuboidal (cube-like shape)columnar (hight is much larger than width)
They are classified according to shape.They have square,cube,colomnar shapes.
