surface area to volume ratio

Hi Friends, Good Evening!!!

Let us learn about "surface area to volume ratio"

Introduction on surface area to volume ratio:

The surface-area-to-volume ratio also called the surface-to-volume ratio and variously denoted sa/vol or SA:V, is the amount of surface area per unit volume of an object or collection of objects. The surface area to volume ratio is measured in units of inverse distance. A cube with sides of length a will have a surface area of 6a² and a volume of a³.

The surface to volume ratio for a cube is thus 6/a. Here we are going to see the formulas for surface area and volume of some regular shapes. Examples to calculate the surface area to volume ratio is given in the following sections.

The surface area in general, is the sum of all the areas of all the figures that cover the surface of the object.

Surface area of cube:

Sum of the areas of all six faces of a cube is its total surface area. Since a cube has all its sides i.e., length, breadth and height equal and each surface is a square.

In words, the surface area of a cube that covers the area of the six squares. The area of one of them is a*a, or a². You can multiply one of them by six since these are all the same, so the surface area of a cube is 6 times one of the sides squared.
