in humans, the sperm cell joins the egg cell at fertilisation to form a single cell, the zygote. This cell and every cell of the developing embryo that it becomes undergoes cell division several times before the embryo attaches to the uterus lining. Cell division is the process where one cell becomes two cells.
The first cell division takes 24 hours. The subsequent divisions each take 8 hours. After 3 days, the embryo has a total volume of 4.2 x 10^-3 mm^3. What is the mean volume of each cell after 3 days? Express your answer in standard form.
Can someone show me how to work this out? I have the answer just not sure how to get there.

Yeah that's the correct answer, how did you work it out?

I understand the beginning part, so 72-48, meaning there are 6 divisions, but that's as far as I get...
