Answer
The volume and surface area of the animal cell are $1.77x10^{-15} m^3$ and $7.07x10^{-10} m^2$. For the bacterial cell the volume and surface area are $5.24x10^{-19} m^3$ and $3.14x10^{-12} m^2$.
Work Step by Step
The calculated surface and volume of both the bacterial and animal cell give us an approximate surface to volume ratio of $6x10^6 m^{-1}$ and $4x10^5 m^{-1}$. This means that while the animal cell has a 3375 fold volume, the membrane surface only increased 225 fold. Given that an internal membrane was included in the equation, the surface to volume ratios would be mostly equal.
