Question: A human brain weighs about 1 kg and contains about 1011 cells. Assuming that each cell is completely filled with water (density 5 = g/mL),

A human brain weighs about 1 kg and contains about 1011 cells. Assuming that each cell is completely filled with water (density 5 = g/mL), calculate the length of one side of such a cell if it were a cube. If the cells are spread out in a thin layer that is a single cell thick, what is the surface area in square meters?
