Detailed explanation-1: -The formula for the surface area of a sphere is 4r2, while the formula for its volume is 4r3/3. As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly).
Detailed explanation-2: -The plasma membrane is the area on the outside of the cell that is referred to as surface area. The volume of a cell is the amount of space it contains. The surface area divided by the volume is the ratio. This shows how much surface area is accessible in relation to the cell’s size.
Detailed explanation-3: -The cell membrane represents a cell’s surface area. What part of a cell represents its surface area? The cytoplasm represents a cell’s volume.
