Volume is defined only for three-dimensional objects. A perfectly flat surface (impossible to find or create in our three-dimensional physical world) cannot have a volume.

To calculate the volume of a flat surface, you need to determine the area of the surface multiplied by its thickness or depth. This will give you the volume of the flat surface.
have a lower surface area-to-volume ratio, allowing for efficient exchange of nutrients and waste products through the cell membrane.
Folds increase the surface area to volume ratio.Imagine a circle with folds all around the edge and another circle the same size with a flat edge. Both circles have the same volume, but the one with the folds has a much larger surface area.
The surface-area-to-volume-ratio
Surface area of cell is divided volume of cell to get surface to volume ratio . If surface area is 8 cm2 and volume is 2 cm2 . The ratio would be 4:1 .
As cell volume increases, the ratio of cell surface area to cell volume decreases. This is because the surface area increases by a square factor while the volume increases by a cube factor. A higher surface area to volume ratio is more favorable for efficient nutrient exchange and waste removal in cells.
