Question 335069
Volume of the earth is {{{5 * 10^14}}} cubic meters.
Volume of a bacteria is {{{2.5 * 10^-16}}} cubic meters.


You divide the volume of the earth by the volume of the bacteria to see how many bacteria would fit in it.


That would be:


{{{(5 * 10^14) / (2.5 * 10^(-16))}}}


{{{5 / 2.5 = 2}}}


{{{10^14 / 10^(-16)}}} = {{{10^(14 - (-16))}}} = {{{10^(14 + 16)}}} = {{{10^30}}}.


The number of bacteria that could fit into the volume of the earth is equal to {{{2 * 10^30}}}.
