Cells Come in a Range of Sizes, and a Variety

Multiple Choice

Cells come in a range of sizes, and a variety of shapes. Assuming a cell type has a conservative cube shape, it may have limits to size, because of the need of materials to diffuse into or out of the cell through the surface area of the cell membrane. Calculate the numerical changes of a cube-shaped cell from an original size of 10 μm × 10 μm × 10 μm.
-If the cell was a cube and you doubled the height,width,and length of the cell,how much would the volume increase?
